Question

For a car with an average fuel efficiency of 34.5 miles per gallon of gasoline, calculate the fuel efficiency in kilometers per liter of gasoline.

a) 9.13 km/L
b) 85.5 km/L
c) 3.72 km/L
d) 14.6 km/L

Answer 1

To convert the fuel efficiency from 34.5 miles per gallon to kilometers per liter, the miles are first converted to kilometers and then gallons to liters, resulting in an efficiency of approximately 14.6 km/L.

Step-by-step explanation:

To calculate the fuel efficiency in kilometers per liter for a car with an average efficiency of 34.5 miles per gallon, we need to use conversion factors to change miles to kilometers and gallons to liters. One mile equals approximately 1.60934 kilometers and one gallon is about 3.78541 liters.

First, converting miles per gallon to kilometers per gallon:

• 34.5 miles/gallon × 1.60934 km/mile = 55.5223 km/gallon

Next, convert kilometers per gallon to kilometers per liter:

• 55.5223 km/gallon ÷ 3.78541 gallons/liter = 14.66 km/liter

Therefore, the correct answer is 14.6 km/L, which is close to one of the options provided (option d).
