Question

A body goes 300 metre in 10 minutes and comes back 100 metre in 5 minutes. what will be its average velocity and average speed?

Answer 1

Explanation:

It is given that a body goes 300 metre in 10 minutes and comes back 100 metre in 5 minutes.

So, Total Distance will be 300 + 100 = 400 m

Total Time taken to cover the distance will be = 10 + 5 = 15 * 60 = 900 second

So, Average Speed is given by Total Distance/Total Time

Average Speed = 400/900

Average Speed = 0.44 m/s

Here, Displacement will be (300-100) = 200 m

So, Average Velocity will be 200/900 = 0.22 m/s
