**Mary**, Sunday, November 11, 2012 at 8:25pmThe basic formula is rate x time = distance. Since the freight train and the passenger train are traveling the same distance, the rate x time for each train equals the other. Let t = the time for the freight train. Then t-2 would equal the time for the passenger train, since it took two hours less time to make the trip. Now you have two equations:

passenger train:

r x t = d, 96 x (t-2) = d

freight train:

r x t = d, 64 x t = d

They both equal d, so they equal each other: 96 x (t-2) = 64 x t

Now solve for t and plug in your equation to find d, the distance.

Note: don't forget to distribute the negative sign on 96(t-2).
