To find the unit rate, we can determine the speed of the motorcycle by dividing the distance traveled by the time taken.
Jeff's motorcycle travels 300 miles in 4 hours, so we calculate the speed as follows:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{300 \text{ miles}}{4 \text{ hours}} = 75 \text{ miles per hour} \]
Now we compare this speed to the speed limit of 65 miles per hour. Since 75 miles per hour is greater than 65 miles per hour, we conclude that the motorcycle is going:
Faster than the speed limit.
