He drove 14 miles per gallon.
Step-by-step explanation:
Total distance = 278.2 miles
Gasoline used = 19.6 gallons
We need to find the unit rate of gallon, therefore, we will divide the total distance covered with the gasoline used to find the distance drove with 1 gallon of gasoline.
Distance per gallon = [tex]\frac{Total\ distance}{Gasoline used}[/tex]
Distance per gallon = [tex]\frac{278.2}{19.6}\\[/tex]
Distance per gallon = [tex]14.19\ miles[/tex]
Rounding of to nearest whole amount;
Distance per gallon = 14 miles
He drove 14 miles per gallon.
