Question 356088
A passenger train's speed is 60 miles per hour, and a freight train's speed is 40 miles per hour. The passenger train travels the same distance in 1.5h less time than the freight train. How long does each train take to make the trip.

passenger train speed = 60 mph
freight train speed = 40 mph
..
let freight train take x hours 
the passenger train will take x-1.5 hours
..
the distance they travel is the same
...
distance = speed * time
...
passenger train distance = 60*(x-1.5)
freight train distance = 40x
..
40x=60(x-1.5)
40x=60x-90
60x-40x=90
20x=90
/20
x=90/20
x=4.5
freight train 4.5 hours
passenger train 4.5-1.5 = 3 hours
