To find the unit rate, you can calculate the speed of the bus from the information given.
If the bus travels 275 miles in 5 hours, you can find the unit rate (miles per hour) by dividing the total miles by the total hours:
\[ \text{Unit Rate} = \frac{275 \text{ miles}}{5 \text{ hours}} = 55 \text{ miles per hour} \]
Now, you compare this unit rate of 55 miles per hour to the current speed of the bus, which is 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.
So, the correct response is: Faster.
