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? Pick
A) 4:5
B) 16:15
C) 9:13
D) 5:15
E) 9:17
Let the distance covered in 1 leap of the dog be x and that covered in 1 leap of the hare be y   Then 3x = 4y   x = 4/3 y   4x = 16/3 y   Ratio of speeds of dog and hare = Ratio of distances covered by them in the same time   = 4x:5y = 16/3 y : 5 = 16:15   Answer is 16:15
