To find the unit rate (speed) at which the motorcycle is traveling, we divide the total distance by the total time:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{500 \text{ miles}}{8 \text{ hours}} = 62.5 \text{ miles per hour} \]
Now we can compare this speed with the speed limit of 65 miles per hour:
- 62.5 miles per hour (motorcycle speed) is less than 65 miles per hour (speed limit).
Therefore, the motorcycle is traveling slower than the speed limit.
The correct response is: Slower than
