a passenger train's speed is 60mi/h, and a freight train's speed is 40mi/h .The passenger train travels the same distance in 1.5 h less time than the freight train. how long does each train take to make the trip?
time for faster train --- t hours
time for slower train === t + 1.5
distance of faster train = 60t
distance of slower train = 40(t+1.5)
but the distances are the same .....
can you take it from there.
