Did you know that you can save fuel and run your car on water
Sabrina J asked:
The fuel efficiency of cars in the US is measured in miles/gallon. However, the rest of the world uses kilometers/liter. A car company advertises the fuel efficiency (“mileage”) of a new model at 45 miles/gallon. What is its fuel efficiency in kilometers/liter? Note: 1 mile = 1.609 kilometers, and 1 gallon = 3.785 liters.
Did you know that you can save fuel and run your car on water
45 miles/gallon * 1.609 kilometers/mile * 1 gallon / 3.785 liters = 19.129 kilometers/liter
so 1mile/gallon = 1.609km/gallon = 1.609km/3.785 liters
easy enough
