Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 20 miles per hour slower than the eastbound train.
If the two trains are 510 miles apart after 3 hours, what is the rate of the westbound train?

Eastbound DATA:
time = 3 hrs ; rate = x mph ; distance = 3x miles
----
Westbound DATA
time = 3 hrs ; rate = x-20 ; distance = 3(x-20) miles
-------
Equation:
dist + dist = 510 miles
3x + 3x-60 = 510
6x = 570
x = 95 mph
x-20 = 75 mph (speed of the westbound train)
------------
