Question

In Europe, gasoline efficiency is measured in km/L. If your car's gas mileage is 36.0mi/gal , how many liters of gasoline would you need to buy to complete a 142-km trip in Europe? Use the following conversions: 1km=0.6214mi and 1gal=3.78L.

Answer 1

`36 (mi)/(gal) * (1 km)/(0.6214 mi)* (1 gal)/(3.78 L) = 15.3 (km)/(L) 142/15.3=9.27L`
