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 variables

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