1. What is MPG and Driving Time?

MPG (Miles Per Gallon) measures a vehicle's fuel efficiency, while driving time estimates how long a trip will take based on distance and average speed.

2. How Does the Calculator Work?

The calculator uses these simple equations:

Where:

• \( miles \) — Distance traveled in miles
• \( fuel \) — Fuel consumed in gallons
• \( speed \) — Average speed in miles per hour (mph)

Explanation: The MPG equation calculates fuel efficiency, while the time equation estimates trip duration.

3. Importance of MPG Calculation

Details: Knowing your vehicle's MPG helps estimate fuel costs for trips and compare fuel efficiency between vehicles. Driving time helps with trip planning.

4. Using the Calculator

Tips: Enter miles traveled, fuel used (in gallons), and average speed. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered good MPG?
A: Typically, 25+ mpg is good for city driving, while 30+ mpg is good for highway. Electric vehicles have MPGe ratings.

Q2: How accurate is the driving time estimate?
A: It's an estimate based on constant speed. Real-world times vary due to traffic, stops, and speed changes.

Q3: Should I use trip odometer or GPS distance?
A: For MPG calculations, odometer distance is typically more accurate as it measures actual wheels turning.

Q4: Does speed affect MPG?
A: Yes, most vehicles have optimal efficiency around 45-60 mph. Higher speeds increase air resistance and reduce MPG.

Q5: How can I improve my MPG?
A: Maintain proper tire pressure, reduce excess weight, avoid aggressive driving, and keep up with vehicle maintenance.
