1. What is Miles Per Hour (MPH)?

Miles per hour (mph) is a unit of speed expressing the number of miles traveled in one hour. It is commonly used in the United States and United Kingdom to measure driving speeds.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Distance \) — Traveled distance in miles
• \( Time \) — Time taken in hours

Explanation: The formula calculates average speed by dividing the distance covered by the time taken to cover that distance.

3. Importance of Speed Calculation

Details: Calculating speed is essential for trip planning, fuel efficiency estimation, and ensuring compliance with speed limits for safe driving.

4. Using the Calculator

Tips: Enter distance in miles and time in hours. For partial hours (e.g., 30 minutes = 0.5 hours). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert minutes to hours?
A: Divide minutes by 60 (e.g., 45 minutes = 45/60 = 0.75 hours).

Q2: What's the average highway driving speed?
A: Typically 55-70 mph in the US, but always follow posted speed limits.

Q3: How accurate is this calculation?
A: It gives average speed over the entire trip. Actual speed may vary at different points.

Q4: Can I use kilometers instead of miles?
A: This calculator uses miles. For km/h, you would need to convert or use a different calculator.

Q5: How does speed affect fuel efficiency?
A: Most vehicles have optimal fuel efficiency between 45-60 mph. Efficiency typically decreases at higher speeds.
