the minute hand of a clock is 9m long. the hour hand clock is 2/3 times longer than the minute clock. how much more distance will minute hand clock more than hour clock in 1 hour/

  1. MathMate

    Length of minute hand: 9m
    Angle moved in one hour = 360°
    Distance = (360/360)*2*π*9m=18π m
    Length of hour hand: 9m*2/3=6m
    Angle moved in one hour = 360/12=30°
    Distance = (30/360)*2*π*6 = π m

    Calculate the difference.
