Practical Examples and Daily Life Uses
Example 1: Daily Commuter Tracking Fuel Efficiency
A person drives 300 miles in a week and uses 10 gallons of fuel.
- MPG = 300 ÷ 10 = 30 MPG
- If fuel costs $3.50 per gallon:
- Total Cost = $35
- Cost per mile = $0.12
This helps commuters understand whether carpooling, public transport, or alternative routes could reduce costs.
Example 2: Road Trip Budget Planning
A family plans a 600-mile road trip. Their vehicle uses 20 gallons of fuel.
- MPG = 600 ÷ 20 = 30 MPG
- If fuel price is $4 per gallon:
- Total Fuel Cost = $80
- Cost per mile = $0.13
This allows travelers to budget fuel expenses before the journey begins.
Example 3: Business Fleet Management
A delivery company tracks fuel usage across vehicles. One truck travels 1,000 miles using 50 gallons.
- MPG = 20 MPG
- Helps managers identify inefficient vehicles and optimize routes.
