    let the normal speed be x
    Normal time in hour-Actual time in hour=reduction in time in hour
    80/x-80/(x+10)=16/60,
    or,x(x+10)=3000,
    or,x=50

    let the normal speed be x
    Normal time in hour-Actual time in hour=reduction in time in hour
    80/x-80/(x+10)=16/60,
    or,x(x+10)=3000,
    or,x=50
