A runs 1 times as fast as B. If A gives B a start of 80 m, how far must the winning post be so that A and B might reach it at the same time?

Answer» Ratio of the speeds of A and B = 5 : 1 = 5 : 3. 3 Thus, in race of 5 m, A gains 2 m over B. 2 m are gained by A in a race of 5 m. 80 m will be gained by A in race of 5 x 80 m = 200 m. 2 Winning post is 200 m away from the starting point.

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 wins by:

Answer» 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.
