Answer
No answer key was printed for this question.
Explanation
Let the distance covered in 1 leap of the dog be x and that covered in 1 leap of the hare be y. 4 16 Then, 3 x = 4 y ⇒ x = y ⇒ 4 x = y. 3 3 ∴ Ratio of speeds of dog and hare = Ratio of distances covered by them in the same time 16 16 = 4x : 5y = y : 5y = : 5 = 16 : 15. 3 3
