A train leaves Boston at 1:00 PM. A second train leaves the same city in the same direction at 3:00 PM. The second train travels 28 mph faster than the first. If the second train overtakes the first at 6:00 PM, what is the speed of each of the two trains?


first train
speed r
time 5 hours
distance 5r

second train
speed 28+r
time 3 hours
distance 3(28+r)


3(28+r)=5r
84+3r=5r
42=r
second train speed
70=r
