Guillermo used the fact that a highway bus traveled 275 miles in 5 hours to find the unit rate. How can he check his answer?

The unit rate is the distance traveled in one hour, measured in miles per hour. Multiply that rate by 5 hours; the hours cancel, and the result should be 275 miles, the total distance. So he should choose “Multiply the unit rate by 5 hours and see if it equals the total distance.”
