Answer:
[tex]14\ \frac{miles}{gallon}[/tex]
Step-by-step explanation:
we know that
To find out the unit rate (number of miles per gallon of gasoline) divide the total miles driven by the total gallons of gasoline used
so
[tex]\frac{278.2}{19.6}\ \frac{miles}{gallons}=14.19\ \frac{miles}{gallon}[/tex]
Round to the nearest WHOLE amount of miles
[tex]14.19\ \frac{miles}{gallon}=14\ \frac{miles}{gallon}[/tex]
