Answer: you will need 22.98 liters of gas to complete a 313 km trip.
Step-by-step explanation:
Suppose your cars gas efficiency is 32.0mi/gal, we would need to convert from miles per gallon to kilometers per liter.
From the information given,
0.6214 miles = 1 kilometer
Therefore,
32 miles = 32/0.6214 = 51.4966 kilometers
Meanwhile,
1 gallon = 3.78 liters
Therefore, the gas efficiency of the car in kilometers per liter would be
51.4966/3.78 = 13.62 kilometers per liter
Therefore, the number of liters of gas that you will need to complete a 313 km trip is
313/13.62 = 22.98 liters
