A car travels 360 miles using 12 gallons of fuel. What is its fuel efficiency in miles per gallon, and how far can it travel on 15 gallons? - Appcentric

Understanding the Context

To determine fuel efficiency, use the basic formula:

Fuel efficiency (MPG) = Total distance traveled ÷ Total fuel used

For the given data:

• Distance = 360 miles
  
• Fuel used = 12 gallons

So,
MPG = 360 ÷ 12 = 30 miles per gallon

Key Insights

This means the car achieves 30 miles per gallon under the tested conditions.

How Far Can the Car Travel on 15 Gallons?

Now that we know the fuel efficiency is 30 MPG, calculating range on 15 gallons is straightforward:

Distance = Fuel (gallons) × Fuel efficiency (MPG)

Distance = 15 × 30 = 450 miles

Final Thoughts

Thus, with 15 gallons of fuel, the car can travel up to 450 miles, assuming consistent driving conditions and optimal engine performance.

Practical Implications for Drivers

Understanding fuel efficiency helps drivers plan long trips more accurately. Knowing that a 30 MPG vehicle covers 450 miles on 15 gallons means planning refueling stops becomes simpler, reducing unexpected fuel shortages. It also aids in cost estimation—in recent fuel price environments, this efficiency translates directly into savings over distance traveled.

Improving Fuel Efficiency

While the example shows solid performance, drivers can further enhance miles per gallon by:

• Maintaining steady speeds and avoiding rapid acceleration
  
• Reducing unnecessary weight
  
• Keeping tires properly inflated
  
• Using cruise control on highways
  
• Scheduling regular maintenance
