Practical Example
Imagine you have:
- Gallons of Fuel: 15 gallons
- MPG: 25 miles per gallon
- Fuel Price per Gallon: $4.00
- Trip Distance: 200 miles
Here’s what you’d get:
- Maximum Miles = 15 gallons × 25 MPG = 375 miles
- Total Fuel Cost = 15 × $4.00 = $60.00
- Cost per Mile = $60 ÷ 375 = $0.160 per mile
- Gallons Needed for Trip = 200 ÷ 25 = 8 gallons
- Fuel Cost for Trip = 8 × $4.00 = $32.00
With this information, you can see if your current fuel is enough and how much your trip will cost.
