A train leaves Miami at 4:00 PM. A second train leaves the same city in the same direction at 8:00 PM. The second train travels 124mph faster than the first. If the second train overtakes the first at 10:00 PM, what is the speed of each of the two trains?

Step-by-step explanation:

The late but fast train traveled for 2 hours while the slow but early train traveled for 6 hours.

              SPEED       TIME     DISTANCE

FAST LATE      r+124         2          d

Catchup means each train traveled equal distance
