Question

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?

Answer 1

1005.68 litres

Explanation:

Steps to answering this question

1. Convert miles to kilometers and gallons to litres
2. Then divide the converted miles by the converted gallons
3. Multiply the value gotten from the above step by 100 km

1 gallon = 3.78541 litres

13.6 gallons x 3.78541 = 51.48 litres

1 mile = 1.60934 km

321.7 miles x 1.60934 = 517.72 km

Litre needed per kilometer = 517.72 km / 51.48 = 10.06

Litres needed for 100 km = 100km x 10.06 = 1005.68 litres
