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
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.
The times are the same, so the answer checks.
