Question

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 80 miles per hour. The westbound train

travels at 70 miles per hour. How long will it take for the two trains to be 360 miles apart?
Do not do any rounding.

Answer 1

Answer: 2.4 hours

Explanation:

Distance = speed x time

1st train = 80t

2nd train = 70t

80t + 70t = 360

t = 360/150 = 2.4 hours

Answer 2

2.4 hours

Explanation:

after an hour the distance between them will be 80+70=150 miles

1 hour .......150 m

x hours .......360 m

x*150=360

x=360/150

x=2.4 hours
