To find the unit rate, we can calculate the speed of the motorcycle by dividing the total distance traveled by the total time taken.
The motorcycle travels 300 miles in 4 hours:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{300 \text{ miles}}{4 \text{ hours}} = 75 \text{ miles per hour} \]
Now we compare this speed to the speed limit:
- Speed of the motorcycle: 75 miles per hour
- Speed limit: 65 miles per hour
Since 75 miles per hour is greater than 65 miles per hour, we can conclude that the motorcycle is traveling faster than the speed limit.
Therefore, the answer is Faster than.
