Question

A sprinter travels a distance of 100 m in a time of 9.42 seconds. What is the sprinter's average speed rounded to 4 sf? m/s

Answer 1

v = 10.6 m/s

Explanation:

Given that,

Distance covered by a sprinter, d = 100 m

Time, t = 9.42 seconds

We need to find the sprinter's average speed. It is equal to the total distance covered divided by the time taken. So,

`v=(d)/(t)\\\\v=(100\ m)/(9.42\ s)\\\\v=10.6\ m/s`

So, the sprinter's average speed is 10.6 m/s.
