In the united states car fuel efficiency is expressed in miles per gallon of gasoline. however fuel efficiency can also br expressed in kilometers per liter of gasoline. if the fuel efficiency of a car is 11.0km/l , what is its fuel efficiency in miles per gallon

The fuel efficiency is 26.3 mpg.

Step 1. Convert kilometres to miles

Efficiency = (11.2 km/1 L) × (0.6214 mi/1 km) = 6.960 mi/L

Step 2. Convert litres to gallons

Efficiency = (6.960 mi/1 L) × (3.785 L/1 gal) = 26.3 mi/gal = 26.3 mpg
