1. What is the Average MPH Formula?

Definition: This calculator computes average speed in miles per hour based on total distance traveled and total time taken.

Purpose: It helps drivers, athletes, and transportation professionals determine their average speed over a journey.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( AS \) — Average speed (miles per hour)
• \( TD \) — Total distance (miles)
• \( TT \) — Total time (hours)

Explanation: The total distance is divided by the total time to get the average speed.

3. Importance of Average Speed Calculation

Details: Calculating average speed helps in trip planning, fuel estimation, and performance analysis.

4. Using the Calculator

Tips: Enter the total distance in miles and total time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Can I use kilometers instead of miles?
A: This calculator uses miles. Convert kilometers to miles first (1 km ≈ 0.621371 miles).

Q2: How do I enter time in minutes?
A: Convert minutes to hours (divide by 60) before entering. For 90 minutes: 90/60 = 1.5 hours.

Q3: What if I have multiple legs with different speeds?
A: This calculates overall average. For multiple legs, sum all distances and all times first.

Q4: Does this account for stops?
A: Yes, if you include stop time in your total time input.

Q5: What's a good average speed for highway driving?
A: Typically 55-70 mph, depending on speed limits and traffic conditions.
