Diana went on a trip over spring break. She traveled 479.4 miles and used 17 gallons of gas. At what unit rate did Diana use gasoline?

Answer 1

To find the unit rate at which Diana used gasoline, we need to divide the total distance traveled by the total amount of gas used.

Unit rate = Total distance / Total gas used

Unit rate = 479.4 miles / 17 gallons

Unit rate ≈ 28.2 miles per gallon

Therefore, Diana used gasoline at an approximate unit rate of 28.2 miles per gallon.
