To find the unit rate, we can determine the speed of the motorcycle by dividing the total distance by the total time.
The 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 can 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 can conclude that:
The motorcycle is going faster than the speed limit.
