Help me please with this word problem?

Question

Two trains leave a train station at the same time. One travels east at 9 miles per hour. The other train travels west at 10 miles per hour. In how many hours will the two trains be 167.2 miles apart?

Answer 1

167.2 divided by 19 =8.8

Answer 2

well, does your problem say how long the trains are?  since some trains are over a mile long, are you measuring the distance between the head ends (engines) or the last cars?  hehe  have fun

Answer 3

The trains are increasing the distance between them at a rate of 19 mph.

167.2 divided by 19 = ?

Answer 4

For a start, this is a mathematical problem, not a word one. But why not post it on the homework help page. It really has nothing to do with this part of the board, other than you have been set a problem involving trains - but it could just have easily been cars or bicycles (at the speed)

Answer 5

X = hours, therefore 9X+10X = 167.2

19X = 167.2

X= 167.2/19

X = 8.8

  9 x 8.8 = 79.20

10 x 8.8 = 88.00

time = 8.8 hours

Answer 6

Just a tip:   it is 24 hrs in a day and 60 min. in a hour

you do the math using your average speed of travel  and the total miles for your destination and the answer is................???
