Question

sarah and her friends are conducting an investigation about speed during their schools field day. they measured the distances for students to run different distances. which two of the following measurements would sarah need to calculate the average speed of a. the time taken to complete the run b. the distance the runner covered c. the runners height d. the runners age e. the runners shoe size

Explanation:

Step1: Recall speed formula

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

Step2: Identify required measurements

To calculate average speed, we need the distance ($d$) the runner covered and the time ($t$) taken to complete the run.

Answer:

A. The time taken to complete the run, B. The distance the runner covered
