Question

A takes three hours more than B to walk a distance of 30 KM. BUT,if A doubles his speed ,he is ahead of B by 1.5 hours. Find their speeds of walking.

Answer 1

Let speed of A be x and speed of B be y. Time taken by A = 30/x Time taken by B = 30/y According to question , 30/x = 30/y +3 - eq1 30/y - 30/2x = 3/2 - eq 2 By solving eq 1 & 2 X= 10/3 km/h Y= 5 km/h
