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?
1 answer
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.
