To calculate the gasoline cost for a 2300-mile trip at an average speed of 46 miles per hour, we need to know the fuel efficiency of the vehicle in miles per gallon (mpg). Let's assume a fuel efficiency of 25 mpg for the vehicle.
The total amount of gasoline required for the trip is:
2300 miles ÷ 25 mpg = 92 gallons
The total cost of the gasoline is:
92 gallons x $4.61/gallon = $423.12
Therefore, the gasoline cost for a 2300-mile trip at an average speed of 46 miles per hour is $423.12.
To calculate the gasoline cost at an average speed of 68 miles per hour, we need to adjust the fuel efficiency of the vehicle. According to the U.S. Department of Energy, higher speeds can significantly reduce fuel efficiency, particularly for vehicles with poor aerodynamics.
Assuming a fuel efficiency of 20 mpg at an average speed of 68 miles per hour, the total amount of gasoline required for the trip is:
2300 miles ÷ 20 mpg = 115 gallons
The total cost of the gasoline is:
115 gallons x $4.61/gallon = $530.15
Therefore, the gasoline cost for a 2300-mile trip at an average speed of 68 miles per hour is $530.15.
