How Long Does 10 Pounds of Gasoline Last?

10 pounds of gasoline typically lasts approximately 4.5 to 5 miles per gallon (mpg) for an average passenger vehicle, depending on the vehicle's fuel efficiency. This equates to about 20 to 22 miles of driving distance.

Explanation:

The duration that 10 pounds of gasoline lasts is influenced by several factors, including the vehicle's fuel efficiency, driving conditions, and the density of the gasoline. The average fuel efficiency for passenger vehicles in the United States is around 25 mpg, but this can vary widely depending on the make and model of the vehicle.

To calculate the distance, we first need to convert the weight of gasoline to volume. The density of gasoline is approximately 6.2 pounds per gallon. Therefore, 10 pounds of gasoline is equivalent to about 1.61 gallons (10 pounds / 6.2 pounds per gallon).

Using the average fuel efficiency of 25 mpg, we can estimate the distance as follows:

1.61 gallons / 25 mpg = 0.0644 gallons per mile

1 / 0.0644 miles per gallon = 15.5 miles per gallon

This is a theoretical maximum, and actual fuel efficiency may vary. However, considering the typical range of fuel efficiency for passenger vehicles, the estimated range of 20 to 22 miles is a reasonable approximation.

It's important to note that fuel efficiency can be affected by various factors, such as driving habits, vehicle maintenance, and road conditions. For example, aggressive driving, which includes rapid acceleration and hard braking, can significantly reduce fuel efficiency. Additionally, maintaining proper tire pressure and regular engine maintenance can improve fuel economy.

According to the U.S. Department of Energy, the average fuel economy for new vehicles in the United States was 25.4 mpg in 2020. This figure includes both passenger cars and light trucks. The actual fuel efficiency of a vehicle can be found in the vehicle's owner's manual or through online resources provided by the Environmental Protection Agency (EPA).

In conclusion, 10 pounds of gasoline generally lasts around 20 to 22 miles for an average passenger vehicle, assuming a fuel efficiency of 25 mpg. However, individual results may vary based on the specific vehicle and driving conditions.
