an olympic runner completes the 200 - meter sprint in 23 seconds. what is the runners average speed? (round your answer to the nearest tenth of a meter per second.) 0.9 m/s 1.2 m/s 8.7 m/s 10.1 m/s

Answer

Explanation:

Step1: Recall speed formula

The formula for average - speed is $v=\frac{d}{t}$, where $d$ is distance and $t$ is time.

Step2: Identify values

Here, $d = 200$ meters and $t=23$ seconds.

Step3: Calculate speed

$v=\frac{200}{23}\approx8.7$ m/s

Answer:

C. 8.7 m/s
