Explanation:

Answer 2

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}=\frac{\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}=(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.
