1. What is MPH?

MPH (Miles Per Hour) 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 vehicle speed and other rates of movement.

2. How Does the Calculator Work?

The calculator uses the basic speed formula:

Where:

• \( Miles \) — Distance traveled in miles
• \( Hours \) — Time taken in hours
• \( MPH \) — Speed in miles per hour

Explanation: This formula calculates average speed by dividing the total distance traveled by the total time taken.

3. Importance of Speed Calculation

Details: Calculating speed is essential for travel planning, fuel efficiency calculations, sports performance analysis, and ensuring compliance with speed limits for safe driving.

4. Using the Calculator

Tips: Enter the distance in miles and time in hours. Both values must be positive numbers. The calculator will compute your average speed in miles per hour.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good MPH for running?
A: For recreational runners, 5-7 mph is common. Elite marathon runners maintain 12-13 mph. Walking speed is typically 3-4 mph.

Q2: How do I convert MPH to other speed units?
A: To convert to km/h, multiply by 1.609. To convert to meters per second, multiply by 0.447.

Q3: What's the difference between MPH and average speed?
A: MPH is the unit, while average speed is the calculation result. Average speed considers total distance and time, not instantaneous variations.

Q4: Can I use this for partial hours?
A: Yes, enter decimal values for hours (e.g., 0.5 for 30 minutes, 1.25 for 1 hour 15 minutes).

Q5: How accurate is this calculation for real-world driving?
A: This gives average speed. Real driving involves stops, traffic, and speed changes, so actual instantaneous speeds will vary.
