Question

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels  18  miles per hour slower than the eastbound train. If the two trains are  300  miles apart after  2  hours, what is the rate of the westbound train? Do not do any rounding.​

Answer 1

66 mph

Explanation:

w = e - 18

2w + 2e = 300

2 (e - 18) + 2e = 300

2e - 36 + 2e = 300

4e - 36 = 300

4e = 300 + 36 = 336

e = 84 mph

w = 66 mph

The westbound train is travelling at 66 mph
