Question

In Europe, gasoline efficiency is measured in km/L. If your car's gas mileage is 32.0 mi/gal , how many liters of gasoline would you need to buy to complete a 142-km trip in Europe

Answer 1

10.44 liters of gasoline.

Step-by-step explanation:

First, we need to convert the units of the car from mi/gal to km/L as follows:

`mileage = 32.0 (mi)/(gal)*(1.609 km)/(1 mi)*(1 gal)/(3.785 L) = 13.60 km/L`

That means that for every liter of gasoline the car travels 13.60 kilometers.

So, to complete a 142-km trip in Europe the volume of gasoline needed is:

`V = (1 L)/(13.60 km)*142 km = 10.44 L`

Therefore, to complete a 142-km trip in Europe we need to buy 10.44 liters of gasoline.

I hope it helps you!
