Question

Time taken by a to take 5 steps is equal to time by b to take 6 steps and by c to take 7 steps. but distance covered in 6 steps of a are equal to 7 steps of b and 8 steps of

c. ratio of their speed is –

Answer 1

The details of time period of each of A,b and C's steps are as folows:

A : B : C = 5 : 6 : 7

But we are concern about the ratio so we need to find the distance as well and it is gives as below:

A : B : C = 6 : 7 : 8

Now we know the formula to calculate speed = distance / time.

Therefore ratio of their speed = 5/6 : 6/7 : 7/8 = 140 : 144 : 147 (Ans)
