1) In a 300 m race A beats B by 22.5 m or 6 sec.What is the
B's time over the course?
Sol: B runs 22.5 m in 6sec.
B runs 300m in =6*300*2/45 =80 sec.
B's time over the course =80 sec.

2) A can run 22.5 m while B runs 25 m.In a kilometre race B
beats A by?
Sol: B runs 25 m ,A runs 45/2 m B runs 1000 A runs
= 1000*45/2*25 =900m B beats A by 100m
3)In a 500 m race, the ratio of the speeds of two contestants
A and B is 3:4.A has a start of 140 m.Then ,A win by B?
Sol: The speeds of A and B =3:4 To reach the winning post A will
have to cover a distance of 500-140 m i.e 360 m while A covers 3m,
b covers 4m A covers 360m B covers 4/3*360=480m Thus when A
reaches the winning post, b covers 480m and therefore remains
20m behind. A wins by 20m.
