Question

Ravi and ramu start from point a and run upto point b and back. Ravi runs at a uniform speed of 10kph. Ramu runs from point a to b at 15kph and returns at 5kph. Which of the 2 will get back to point a first?

Answer 1

Answer:

They will reach at the same time.

Step-by-step explanation:

This is a question on average speed.

The average speed for Ravi is :

(10 + 10) / 2 = 10 km/h

The average speed for Ramu is :

(15 + 5) / 2 = 20/2 = 10

= 10 km/h

Since they all have the same average speed they will reach point a at the same time.

Answer 2

Answer:

They will reach at the same time.

Step-by-step explanation:

This is a question on average speed.

The average speed for Ravi is :

(10 + 10) / 2 = 10 km/h
