Question

A person walks 15m in 5s and then walks back 5m in 1s. What is the average speed?

Options

Choose one · Correct answer highlighted

Explanation

Average speed = total distance / total time. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 3 m/s as the result, so option A is correct.
