    Efficiency of A: 1 36 Efficiency of B 1 32

    Finish: 1 36 9+14 1 32=1 4+7 16=11 16

    Remaining: (1-11 16) (1 36 + 1 32) = 90 17

    x+solution:x=

    x=test: Substitute x= into the equation and make a noise.

    Left = Right.

    So, x= is the solution of the equation.

    According to the inscription, the time ratio of B and C is 45:50 = 9:10, that is, the velocity ratio is 10:9.

    The time ratio of A and B is 60:75 = 4:5, that is, the velocity ratio is 5:4, and the velocity ratio of A, B and C is 25:20:18.

    The velocity ratio of A and C is 25:18.

    Find the ratio.
