Question

Philoid · Accepted Answer

Speed = distance/time

Let the speed of Ajeet be ‘a’ and speed of Amit be ‘b’.

Given, while covering distance of 30 km. Ajeet takes 2 hours more than Amit. If Ajeet doubles his speed, he would take 1 hour less than Amit.

Also,

Adding the two equations

⇒ 30/a - 15/a = 3

⇒ a = 5 km/hr

Thus, 30/5 – 30/b = 2

⇒ b = 7.5 km/hr
