1. A sprinter races in the 100 meter dash. It takes him 10 second to reach the finish line What is his average velocity?

v = 10 m/s

Explanation:

Given that,

Distance covered by a sprinter, d = 100 m

Time taken by him to reach the finish line, t = 10 s

We need to find his average velocity. We know that velocity is equal to the distance covered divided by time taken. So,

v = d/t

Hence, his average velocity is 10 m/s.
