Q9. In a race of 100 m, A gives a start of 10 m to B. Despite this, A wins the race by 20 m. What is the ratio of the speed of A and B?

(a) 10: 7

(b) 8: 2

(c) 5: 3

(d) 6: 4

S9. Ans.(a)

Sol. Time taken by A to cover 70 m = Time taken by B to cover 100 m

Since the distance is constant, the ratio of speed of A and B = 10 : 7
