Question 302571: A passenger train can travel 240 miles in the same amount of time it takes a freight train to travel 160 miles. If the rate of the freight train is 20 miles per hour slower than the rate of the passenger train, find the average rate of each. Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! p*t=240
f*t=160
f=p-20
t=240/p
t=160/f
240/p=160/f
240/p=160/(p-20)
3/p=2/(p-20)
2p=3p-60
60=p
f=40
t=4
