A cat leaps 5 leaps for every 4 leaps of a dog, but 3 leaps of the dog are equal to 4 leaps of the cat. What is the ratio of the speed of the cat to that of the dog?

Question: A cat leaps 5 leaps for every 4 leaps of a dog, but 3 leaps of the dog are equal to 4 leaps of the cat. What is the ratio of the speed of the cat to that of the dog?

Solution:
Given;
3dog = 4 cat
Or, dog/cat = 4/3

Let cat's 1 leap = 3 meter and dogs 1 leap = 4 meter

Then, ratio of speed of cat and dog = (3 × 5) / (4 × 4) = 15 : 16
