If the fuel efficiency of a car is 22 miles per gallon, what is its fuel efficiency in kilometers per liter?

(1 mi = 5280 ft, 1 inch = 2.54 cm, 1 L = 1.057 quarts, 4 quarts = 1 gallon)​

Answer:

9.37 km/ L.

Step-by-step explanation:

Fuel efficiency= 22 miles / gallon

Let's convert the miles to kilometers using the given factors:

(22 * 5280 * 12 * 2.54)/100,000= 35.40 km

Easier form to convert mi to km:

22mi * 1.60934= 35.40 km.

Converting gallons to L with the given factors:

1 gallon * 4= 4 quarts

1.057 quarts ---- 1L

4 quarts ---------- x

x= (4 * 1)/ 1.057 = 3.78 L

Easier way to convert gallons to L:

1 gallon * 3.785= 3.785 L.

Now, we unive and divide the new values:

35.40 km / 3.78 L= 9.37 km/ L.

Note that this result might be slightly distortioned due to the use of many factors to convert units. However, is a good estimate of the exact value.
