It takes a bus 6 hours to take a trip. the train takes only 4 hours to make the same trip. the train travels at a rate of speed that is 25 mph more than the speed of the bus. what is the rate of the bus and the rate of the train?
Let the speed of the bus = S
The speed of the train = S + 25
6S = 4[S + 25], solve for S
S = 50 mph - speed of the bus
50 + 25 = 75 mph - speed of the train
