Formula Used

The calculation is based on this simple formula:

Total Cost = (Distance / MPG) × Price per Gallon

Where:

Distance is the total miles you'll travel
MPG is your vehicle's miles per gallon rating
Price per Gallon is the current cost of gasoline in your area

This formula gives you a precise estimate of how much you'll spend on gas for your trip.

Worked Example

Let's say you're planning a 300-mile road trip in a car that gets 25 miles per gallon, and the current gas price is $3.50 per gallon.

Using our formula:

Total Cost = (300 miles / 25 MPG) × $3.50/gallon = 12 gallons × $3.50/gallon = $42.00

So for this trip, you would need 12 gallons of gas and the total cost would be $42.00.

Note: Real-world results may vary slightly due to factors like traffic conditions, driving habits, and changes in gas prices.
