To find the unit rate of the bus, we can calculate its speed based on the given distance and time. The bus travels 275 miles in 5 hours, so the unit rate (speed) is:
\[ \text{Unit Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{275 \text{ miles}}{5 \text{ hours}} = 55 \text{ miles per hour} \]
Now, we compare this unit rate of 55 miles per hour to the bus's current speed of 59 miles per hour.
Since 59 miles per hour is greater than 55 miles per hour, the bus is traveling faster than the unit rate.
The correct response is: Faster
