A freight train leaves town, traveling at 35 mph. One hour later a Passenger train leaves town, Traveling on a parallel track at 40 mph. How far from town will the passenger train catch the freight train? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! D=RT
D=35*T FOR THE FREIGHT TRAIN.
D=40(T-1) FOR THE PASSENGER TRAIN.
35T=40(T-1)
35T=40T-40
35T-40T=-40
-5T=-40
T=-40/-5
T=8 HOURS ANS.
PROOF:
35*8=40(8-1)
280=40*7
280=280
