To reach the winning post A will have to cover a distance of (500 - 140)m, i.e., 360 m.

While A covers 3 m, B covers 4 m.

While A covers 360 m, B covers 4 x 360 m = 480 m.
3
Thus, when A reaches the winning post, B covers 480 m and therefore remains 20 m behind.

A wins by 20 m.

A wil have to cover the distance 500-140=360m
therefore 3/4 =360/x
x = 360* (4/3)
x= 480
so 500 - 480 = 20
A wins by 20m.
