GP 2 Week 2
A train leaves Chicago traveling to LA and is traveling at 40 mph. 2 hours later another train leaves heading in the same direction. The second train is traveling at 60 mph. How long until the second train passes the first train?
Since the first train is two hours ahead of the second train, you would have to mulitply 40 mph by the time (2 hours). The first train has traveled 80 mph in two hours. For the second train you would have to mulitply 60 mph by the time also. The second train has traveled 120 mph. In two hours the second train will pass the first train. England 5
The first train is going 40mph and the second train is going 60mph and it left the station 2 houers after so that means the second train will pass the first one in two hours.
Train 1 left the station at 40MP/H and Train 2 leaves at 60MP/H So you'd have to assume that train left 2 hours after train 1 Train1 is 40*2=80 trian2 is 60*2=120 So it will only take 2 hours to pass Train 1
since the 1st train is going 40mph. and the 2nd train is going 60mph. wouldnt that mean the 2nd train is going 20pmh more times the 1st trains speed so the 2nd train will pass in 2 hours
If the first train leaves two hours earlier travel 80 mph in two hours. Then the second train which travels 120 mph in two hour the second train will pass the first train in its first two hour.the first train will be passed in its first four hours
England2 the second train will past the first one in two hours because the second one is traveling 2 times faster so in 2 hours the first train will travel 80 mph and then the second one will travel 120 mph.
England 1st The second train will past the first train in two hours because the first train is moving at 40 mph and the second train is moving at 60 mph so in two hours the first train would be at 80 mph and the second train would be at 120 mph.
England 5th In two hours the second train would pass the first because the first train is going 40 mph but the second is going 60 mph.After two hours the first train would be at 80 miles as the second train would be at 120
England 1 The 2nd train will past the 1st train in 2 hours because the 1st train is moving at 40 mph and the 2nd train is moving at 60 mph so in two hours the 1st train would be at 80 mph and the 2nd train would be at 120 mph. armani ford
if the #1 train is going 40 then the #2 train is going 60 and the #1 train is 2 hours ahead of the #2 train so you multiply 40x2=80mph and the #2 train is going 60 so you multiply 60x2=120mph so it will be 2 hours till the #2 train passes the #1 train
The first train moved 80 mph in 2 hours (40×2=80). The second train was traveling 60 mph which means it moves 120 mph in 2 hours (60×2=120). So the second train would pass the first train in 2 hours.
The first train moved 80 miles per 2 hours. The second train went 120 miles per 2 hours. So then the 2nd train would pass the first train within 2 hours.
Since the first train is already 2 hours ahead you have to multiply 40 mp by 2.The first train is 80 mph.For the second train multiply 60 by 2 also.The second train has traveled 120 mph in 2 hours it will take the second train 2 hours to pass the first.
The first train was 40 miles per hour. The second train was 60 miles per hour. The secind train past the first train 7 hours into the trip. The second train traveled a total of 300 miles in 7 hours while train 1 only traveled 280 miles in 7 hours
multiply 40mph by 2 to get 80.then multiply 60mph by 2. the second train traveled 120 mph in two hours. It will take the second train two hours to pass the first.
train 1 40 miles per hour. train2 was 60 miles per hour. the second train past the first train 7 hours into the trip. the second train traveled a total of 300 miles in 7 hours while 1 only traveled 280 miles in 7 hours.
The first train is going 40mph and the second train is going 60mph and it left the station 2 houers after so that means the second train will pass the first one in two hours.
The first Train is traveling at 40 Mph (2 Hours) after the frist train departed from the train station. The secound train was traveling at 60 Mph If you multiply 40 Mph x (2 Hours) it will become 80 Mph. Mulitply 60 Mph x (2 Hours) it will become 120 Mph. The second train will drive past the frist train in 2 Hours England 5
Since the first train is 2 hours ahead of the second train, you would have to multiply 40 mph by 2 hours. The first train has traveled 80 mph in 2 hours. For the second train you would have to multiply 60 mph by 2 hours also. The second train has traveled 120 mph. In 2 hours the second train will pass the first train. ~England 5~
the first train left two hours ago so it so would almost take 2 1/2 hours to passes the first one so 2 1/2 hours .the first train moves at 40 .then the second moves at 60. they would have to end up passing it in 2 1/2 hours.
the first train is traveling at 40 mph (2 hours) after the first train departed from the train station.the second train was traveling at 60 mph if multiply 40 mph x (2 hours) it will become 80 mph . multiply 60 mph x 2 hours it will be 120 mph the second train will drive pass the first train in 2 hours. ~England 3~
Since the first train is two hours ahead of the second train, you would have to muliply times (2 hours). The first train has traveled 80 mph in two hours. The second train has traveled 120 mph. In two hours the second train will pass the first train.
If the first train leaves two hours before the second train and is traveling at 40 mph, and the second train is traveling at 60 mph, if you multiply 40x2, it will be 80 mph. The second train will pass the first train within two hours.
the first train left the station 2 hours ahead of train 2. the first train traveled at 80 mph in two hours so. so the second train will have been going 120 mph. the second train will pass the first train in 1 2 hours at 120 mph. Alan Harold Jackson pr 2
Will the first train is traveling at a constants speed of 40 Mph for (2 Hours). Then when the first train departed from it's train station.The second train was moving at 60 Mph. Multiply 40 x 2 Hours then the answer will be 80. So now you times 60 x 2 also. And you get 120 Mph.
The first train is traveling at 40 mph(2 hrs) after the first train departed from the train station. The second train was traveling at 60 mph if multiply 40 mph x (2 hrs)it will become 80mph. multiply 60 mph x 2 hrs it will be 120 mph the second train will pass the first train in two hrs.
Train 1 Is Going 40 Mph . Train 2 Is Going 60 Mph . So It Will Take 2 Hours For Train 2 To Pass Train 1 . Train 2 Is Faster Than Train 1. -JacksonP7th-
I agree with corrin b/c when u multiply 40 times 2 u get 80. And when u find 60times 2 u get 120. So the answer is it will take train 2, 2 hours to reach train 1
i think the train will get there in 2 hours, because if you multiply 40mph by 2hours it would the be 80 mph. then multiply 60mph by 2hours also then that would be 120mph so then the second train will pass the first train in 2 hours.
The train would be there in 2 hrs. Because if you multiply 2hrs. By 40mph it would make 80mph. Next you multiply 60mph by 2hrs. Then that would be 120mph so the second would pass the first train in 2hrs.
England 7 The 1st train is two hours ahead of the 2nd train, you would have to mulitply 40 mph by the time.The 1st train has traveled 80 mph in two hours. For the 2nd train you would have to mulitply 60 mph by the time also. The second train has traveled 120 mph. In two hours the 2nd will pass the first train.
England 7 The first train left two hours before the second one. The first train is going 40 mph. The second train is going 60 mph. The first train would have gone 80 miles before the other one departed. The second train would then have gone 120 miles in 2 hours. In 1 and a half to two hours the second train will pass the first.

because the first train is moving 40 mph. the second train is moving 2x as fast. the train will pass in 2 hours.
ReplyDeleteThe first train moves 40mph the second moves 60mph there for the second train moves faster than the first train so it will pass in 2 hours

ReplyDeletethe 1st train is moving 40mph and the 2nd train is moving 60mph which is 20 more mph then the 1st so in 2hours the 2nd train will pass the 1st
ReplyDeleteJACKSON 2
Train 1 left the station at 40MP/H and Train 2 leaves at 60MP/H
ReplyDeleteSo you'd have to assume that train left 2 hours after train 1
Train1 is 40*2=80
trian2 is 60*2=120
So it will only take 2 hours to pass Train 1
The first train is moving 40mph. The second train is moving 60mph. So then the second train will past the first train in 2 hours

the #1 train was going 40mph and the #2 train was going 60mph so the #2 train would pass the first train in 2 hours
ReplyDeleteif the #1 train is going 40 then the #2 train is going 60 and the #1 train is 2 hours ahead of the #2 train so you multiply 40x2=80mph and the #2 train is going 60 so you multiply 60x2=120mph so it will be 2 hours till the #2 train passes the #1 train
ReplyDeleteIt will take the second train 2 hours before it passes the first train
ReplyDeleteEngland 2
ReplyDeleteIt will take the second train two hours to pass the first train because train 2 left after two hours and was traveling 20 more mph.
The first train moved 80 mph in 2 hours (40×2=80). The second train was traveling 60 mph which means it moves 120 mph in 2 hours (60×2=120). So the second train would pass the first train in 2 hours.
