Q. A particular car has a fuel efficiency of

8

liters of gasoline per

100

kilometers. What is the fuel efficiency in miles per gallon? Round to the nearest integer.

\newline

(There are approximately

1

.

6

kilometers in

1

mile, and approximately

3

.

8

liters in

1

gallon.)

Convert kilometers to miles: Convert kilometers to miles by dividing by $1.6$ , since there are approximately $1.6$ kilometers in a mile.
Convert liters to gallons: Convert liters to gallons by dividing by $3.8$ , because there are approximately $3.8$ liters in a gallon.
Calculate fuel efficiency: Calculate the fuel efficiency in miles per gallon by dividing the miles by the gallons.
Round fuel efficiency: Round the fuel efficiency to the nearest integer.
