Question

what is the average speed in m/s over the first 10 seconds? do not include units in your answer. distance (meters) vs. time (seconds)

Explanation:

Step1: Recall speed formula

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

Step2: Determine distance and time from graph

From the graph, at $t = 10$ seconds, the distance $d=50$ meters and the time $t = 10$ seconds.

Step3: Calculate average speed

Substitute $d = 50$ meters and $t = 10$ seconds into the formula $v=\frac{d}{t}$, so $v=\frac{50}{10}=5$.
