1. What is Speed?

Speed is a measure of how quickly an object moves from one place to another. It is calculated as the distance traveled divided by the time taken to travel that distance.

2. How Does the Calculator Work?

The calculator uses the basic speed equation:

Where:

• \( Speed \) — Measured in km/h or mph
• \( Distance \) — Distance traveled (km or miles)
• \( Time \) — Time taken (hours)

Explanation: The equation shows the direct relationship between distance and speed, and the inverse relationship between time and speed.

3. Importance of Speed Calculation

Details: Calculating speed is essential for planning travel time, determining fuel efficiency, setting exercise goals, and analyzing athletic performance.

4. Using the Calculator

Tips: Enter distance in kilometers or miles, time in hours. All values must be valid (distance > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between speed and velocity?
A: Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Q2: How do I convert km/h to mph?
A: Multiply km/h by 0.621371 to get mph. This calculator does the conversion automatically based on your distance unit selection.

Q3: Can I use this for running pace calculations?
A: Yes, though runners often prefer minutes per kilometer/mile. You can convert speed to pace by taking the reciprocal (60/speed gives minutes per km/mile).

Q4: What if my time is in minutes?
A: Convert minutes to hours by dividing by 60 before entering the value (e.g., 30 minutes = 0.5 hours).

Q5: How accurate is this calculator?
A: It provides precise calculations based on your inputs. Accuracy depends on the precision of your distance and time measurements.
