🔍 Practical Example

Let’s say you drove 300 miles on a trip and used 12 gallons of fuel. The average price of gas during your trip was $3.50 per gallon.

1. Distance: 300 miles
2. Fuel Used: 12 gallons
3. Fuel Price: $3.50

After clicking Calculate, you’ll see:

• MPG: 25.00
• Cost per Mile: $0.14
• Total Trip Cost: $42.00
• Efficiency Rating: Good

This means your car is performing at a good efficiency level, and you spent $42 in fuel for the entire trip.
