Question

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at
95
miles per hour. The eastbound train travels at
105
miles per hour. How long will it take for the two trains to be
280
miles apart?
Do not do any rounding.

Answer 1

Answer 2

First train travels 95mph
Second train travels 105mph
Distance = rate * time
So if we model time as x:
95x + 105x = 280.

Can you solve it from here? Or do you have trouble understanding how I came up with the equation?

Answer 3

I got x=7/5

Answer 4

@mhchen ?

Answer 5

Yeah same here. So 7/5 of an hour. (Or 1.4 hours)

Answer 6
