A dog takes 4 leaps for every 5 leaps of a hare but 3 leaps of a dog are equal to 4 leaps of the hare. Compare their speeds.

Question 1

Question 2

Let the distance covered in 1 leap of the dog be x and that covered in 1 leap of the hare by y.

Then , 3x = 4y

x = 4y/3

4x = 16y/3

Ratio of speeds of dog and hare = Ratio of distances covered by them in the same time

= 4x : 5y = 16/3 y : 5y =16/3 : 5 = 16:15
