Question

In Europe, gasoline efficiency is measured in km/L. If your car’s gas mileage is 25.0 mi/gal, how many liters of gasoline would need to buy to complete a 250 km trip to Europe? Use the following conversions: 1 km= 0.6214 mi and 1 gal = 3.78L

Answer 1

Answer:

$V=23.5L$

Explanation:

Hello,

In this case, it is convenient to compute the car's mileage in km/L as follows:

$25.0\frac{mi}{gal}*\frac{1km}{0.6214mi}*\frac{1gal}{3.78L}=10.64\frac{km}{L}$

In such a way, since the distance is measured to be 250 km, the volume requirement is:

$V=\frac{250km}{10.64kg/L}\\ \\V=23.5L$

Regards.
