Question

A new hybrid car sold in the United States reports a fuel usage of 54mpg Write the equivalent rate in kilometers per liter. Round your answer to the nearest hundredth, if necessary.

Answer 1

To convert 54 miles per gallon (mpg) to kilometers per liter (km/L), use the conversion factors of 1 mile = 1.60934 km and 1 gallon = 3.78541 L to get approximately 22.98 km/L.

Step-by-step explanation:

To convert the fuel usage of a hybrid car from miles per gallon (mpg) to kilometers per liter (km/L), we need to know the conversion factors between miles and kilometers, and gallons and liters. Specifically, 1 mile is approximately 1.60934 kilometers, and 1 gallon is approximately 3.78541 liters. Therefore, to convert 54 mpg to km/L, the following calculation is performed:

54 mpg × (1.60934 km / 1 mile) × (1 gallon / 3.78541 L) = 22.98 km/L (rounded to two decimal places).

Thus, the equivalent rate is 22.98 km/L.
