Question

A and B run a 100m race. A beats B by 25m, what is the ratio of the speed of A to that of B?​

Answer 1

Answer:

4 : 3

Step-by-step explanation:

let time = T

Distance covered by A in time T = 100m

distance covered by B in same time T = 100m - 25m = 75m

now,

speed of A = $\frac{distance }{time}$

                 = $\frac{100}{T}$

and,

speed of B = $\frac{distance}{time}$

                 = $\frac{75}{T}$

since,

        ratio of their speed = speed of A : speed of B

                                      = $\frac{100}{T} :\frac{75}{T}$

                                      = 100 : 75

                                      = 4 : 3
