Question

If a car has an EPA mileage rating of 30 miles per gallon, what is this rating in kilometersper liter? (1 L = 1.06 qt)A) 200 km/L B) 180 km/L C) 70 km/L D) 13 km/L E) 11 km/L

Answer 1

To convert miles per gallon to kilometers per liter, we need to use the conversion factor of 1 mile = 1.60934 kilometers and 1 gallon = 3.78541 liters (1 quart = 0.946353 liters, so 1.06 quarts = 1 liter).

So, first we need to convert miles per gallon to kilometers per gallon:

30 miles per gallon = 30 x 1.60934 kilometers per gallon
= 48.2802 kilometers per gallon

Then we need to convert gallons to liters:

1 gallon = 3.78541 liters
So, 48.2802 kilometers per gallon = 48.2802 kilometers per 3.78541 liters
= 12.754 kilometers per liter

Therefore, the answer is D) 13 km/L (rounded to the nearest whole number).
To convert the EPA mileage rating of 30 miles per gallon to kilometers per liter, you can follow these steps:

1. Convert miles to kilometers: 30 miles * 1.60934 km/mile = 48.2802 km
2. Convert gallons to liters: 1 gallon * 3.78541 L/gal = 3.78541 L
3. Calculate kilometers per liter: 48.2802 km / 3.78541 L = 12.754 km/L

So, the EPA mileage rating of 30 miles per gallon is approximately 13 km/L (rounded to the nearest whole number), which is answer choice D.
