A certain European automobile has a gas mileage of 17 km/L. What is the gas mileage in miles per gallon?

검증된 단계별 안내

Identify the conversion factors needed: 1 mile = 1.60934 kilometers and 1 gallon = 3.78541 liters.

Convert kilometers to miles by dividing the given kilometers per liter (17 km/L) by the conversion factor for kilometers to miles (1.60934 km/mile).

Convert liters to gallons by multiplying the result from the previous step by the conversion factor for liters to gallons (3.78541 L/gallon).

Combine the conversions to find the gas mileage in miles per gallon (mpg).
