Answer: 10 ¹/₂ miles per gallon
Step-by-step explanation:
The gas mileage of the camper refers to the distance (in miles for this question) that the camper can travel on 1 gallon of gas.
The camper can travel 3¹/₂ miles on ¹/₃ gallons so the mileage is:
= Distance traveled/ Gallons used
= 3¹/₂ ÷ ¹/₃
= 7/2 * 3/1
= 21 / 2
= 10 ¹/₂ miles per gallon
