Question
A train leaves Atlanta at 1:00 PM. A second train leaves the same city in the same direction at 5:00 PM. The second train travels 48 mph faster than the first. If the second train overtakes the first at 9:00 PM, what is the speed of each of the two trains?

Since the first train coves the same distance in twice the time, it must have half the speed. So, the trains must be going at 48 and 96 mph.
