Question

If a race averages 125 miles per hour for 4 hours, how far does the car travel? Use the number line to help you find the answer.

$\begin{gathered} \text{distance}=\text{speed}\cdot\text{time} \\ \text{distance}=125\cdot4 \\ \text{distance}=500\text{ miles} \end{gathered}$

Using the number line, we have:
