Find the speed of each train.Answer by solver91311(16885)   (Show Source): You can put this solution on YOUR website!Remember that distance equals rate times time, or . If the rate of the freight train is r, then the rate of the passenger train is r + 14. We can rewrite as . For the freight train: , and for the passenger train: . We know that the times are equal because the problem says "same time", so we can say: To solve a proportion, first cross-multiply: The speed of the freight train is 66 mph, and the speed of the passenger train is 66 + 14 = 80 mph. Check: hours hours The times are the same, so the answer checks.
