A passenger train's speed is 60 mi/h, and a freight train's speed is 40 mi/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?

  • algebra - ,

    Let D=distance
    Time for passenger = D/60
    Time for freight = D/40

    "The passenger train travels the same distance in 1.5 h less time than the freight train. "
    D/40 - D/60 = 1.5

    Can you complete the rest?
