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 cars gas efficiency is 30.0mi/gal. How many liters of gas will you need to complete a 135 km trip. Use conversions 1gal=3.78L and 1km=0.6214mi.

Answer: you will need 10.57 liters of gas.

Step-by-step explanation:

The gas efficiency of your car is 30.0mi/gal. The first step is to convert from miles per gallon to kilometers per liter.

0.6214 miles = 1 kilometer

30 miles = 30/0.6214 = 48.28 kilometers

Also,

1 gallon = 3.78 liters

Therefore, the car's gas efficiency in kilometers per liter is

48.28/3.78 = 12.77 kilometers per liter

Therefore, the number of liters of gas that you will need to complete a 135 km trip is

135/12.77 = 10.57 liters
