Question

TWO trains leave the station at the same time, one heading west and the other east. The westbound train travels at 85 miles per hour. The eastbound train

travels at 95 miles per hour. How long will It take for the two trains to be 396 miles apart?
Do not do any rounding.

Answer 1

Answer is 2.2 hours

Step by step

We know distance = rate x time

Distance is 396
Rate is 85 + 95 = 180 mph
Time is what we are looking for

D = R*T
396 = 180 * T

divide both sides by 180 to solve for T

396/180 = 180/180 T

2.2 hours = Time
