Question

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

20
miles per hour faster than the westbound train. If the two trains are
850
miles apart after
5
hours, what is the rate of the eastbound train?
Do not do any rounding.

Answer 1

Let n be the westbound train, and n+20 be the eastbound. Then:
5n+5(n+20)=850
10n=750
n=75 mph
n+20=95 mph
