You decide to take your car on a drive through Canada, where gas is sold in liters and distances are measured in kilometers. Suppose your car's gas efficiency is 39.0 mi/gal. How many liters of gas will you need to complete a 213 km trip? Use the conversions 1 gal = 3.78 L and 1 km = 0.6214 mi.

12.846 liters

Step-by-step explanation:

Efficiency of car is 39.0 mi/gal

using the conversion given, converting the efficiency of the car from miles/gallon to kilometers/liters.

So, 39.0 mi/gal : 2.352 km/liter

16.5808 km/liter

if 16.5808 km/liter is consuming gas of 1 liter

therefore, for 213 km, it takes gas = 213 / 16.5808

=> 12.846 liters

Thus, you will need 12.846 liters of gas will you need to complete a 213 km trip
