Question

A sprinter travels a distance of 200 m in a time of 20.03 seconds.

Answer 1

Given:

Distance traveled by sprinter = 200 m

Time taken by sprinter = 20.03 seconds

To find:

The sprinter's average speed rounded to 4 sf.

Solution:

We know that,

$\text{Average speed}=\dfrac{\text{Distance}}{\text{Time}}$

It is given that, the sprinter travels a distance of 200 m in a time of 20.03 seconds.

$\text{Average speed}=\dfrac{200}{20.03}$

$\text{Average speed}=9.985022466$

$\text{Average speed}\approx 9.985$

Therefore, the average speed of the sprinter is 9.985 m/sec.
