Question

suppose a rollerblade racer finished a 132 - meter race in 18 seconds. what is the average speed of the rollerblade racer? a 0.136 m/s b 2.376 m/s c 7.33 m/s d 2376 m/s

Explanation:

Step1: Recall speed formula

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

Step2: Substitute values

Given $d = 132$ m and $t=18$ s, so $v=\frac{132}{18}$.

Step3: Calculate result

$\frac{132}{18}\approx7.33$ m/s.

Answer:

C. 7.33 m/s
