Question

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 12 miles per hour slower than the westbound train. If the two trains are 400 miles apart after 2 hours, what is the rate of the eastbound train? No Rounding.

Answer 1

This is a classic Distance-Rate-Time problem

let the speed of slower train be x mph
then speed of faster train is x+12 mph

2x + 2(x+12) = 400

solve for x

Answer 2

Thanks you! I got the answer!
