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 you need to buy to complete a 142-km trip in europe? use the following conversions: 1km=0.6214mi and 1gal=3.78l. can someone show me how you got the answer?

You would need to buy 13.3 L of gasoline to complete the trip.

Step 1. Convert kilometres to miles

Distance = 142 km × (0.6214 mi/1km) = 88.24 mi

Step 2. Calculate the gallons of gas

V = 88.24 mi × (1 gal/25.0 mi) = 3.530 gal

Step 3. Convert gallons to litres  

V = 3.530 gal × (3.78 L/1 gal) = 13.3 L
