1. What is Average Speed?

Definition: Average speed is the total distance traveled divided by the total time taken to travel that distance.

Purpose: It helps determine the overall speed of a journey when speed may have varied at different times.

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 for the entire journey.

3. Importance of Average Speed Calculation

Details: Calculating average speed helps in trip planning, fuel estimation, and comparing different routes or transportation methods.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can I use kilometers instead of miles?
A: Yes, but be consistent - use kilometers for both distance and km/h for the result.

Q2: How do I enter time that includes minutes?
A: Convert minutes to hours (e.g., 30 minutes = 0.5 hours).

Q3: What's the difference between average speed and instantaneous speed?
A: Average speed is for the entire trip, while instantaneous speed is at a specific moment.

Q4: Why is my average speed lower than my usual driving speed?
A: Average speed includes stops, traffic, and slowdowns, not just moving time.

Q5: Can this be used for running or cycling?
A: Yes, it works for any activity where you can measure distance and time.
