David drives 168 miles a week for work. he fills his gas tank twice a week. each fill up is for 12 gallons. assuming he uses all of the gas each week and only uses the car to travel to and from work, what is the gas mileage of his car? (gas mileage = miles/gallons)

David's car gives mileage 7 miles per gallon

Step-by-step explanation:

Gas mileage =

=

= 7 miles per gallon

David's car gives mileage 7 miles per gallon
