Answer 2

We have been given that Federica used 13.4 gallons of gasoline to drive 448.9 miles and we have to find out average number of miles she drove per gallon of gasoline.

In order to find out average number of miles Federica drove per gallon of gasoline we will divide total number of miles she drove by the total number of gallons of gasoline she used in driving total number of miles.

$\frac{448.9}{13.4} miles/gallon$

After simplifying our expression we will get

$\frac{448.9}{13.4}=\frac{67}{2}=33.5 miles/gallon$

Therefore, the average number of miles that  Federica drove per gallon of gasoline is 33.5 miles per gallon.
