Question

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 90 miles per hour. The westbound traintravels at 70 miles per hour. How long will it take for the two trains to be 224 miles apart?Do not do any rounding.

Answer 1

Answer

time = 1.4 hours

Explanation:

Two trains moving in different directions

One move due east and another move due west

Distance = rate x time

For train moving in opposite direction, the total rate will be sum together

Rate due east = 90 miles per hour

Rate due west = 70 miles per hour

Total rate = rate due east + rate due west

Total rate = 90 + 70

Total rate = 160 miles per hour

Distance = 224 miles

Calculate the time?

Distance = rate x time

time = distance / rate

time = 224/160

time = 1.4 hours

Therefore, it will take the two trains 1.4 hours to be 224 miles apart
