1. What is Speed Calculator?

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

Purpose: It helps travelers, athletes, and transportation professionals determine average speed for planning and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Speed (kilometers per hour)
• \( D \) — Distance traveled (kilometers)
• \( T \) — Time taken (hours)

Explanation: The distance is divided by time to calculate the average speed over that period.

3. Importance of Speed Calculation

Details: Accurate speed calculation helps in travel planning, fuel efficiency estimation, and performance measurement in sports.

4. Using the Calculator

Tips: Enter the distance in kilometers and time in hours. For partial hours (e.g., 30 minutes = 0.5 hours). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for miles and mph?
A: No, this calculator is specifically for kilometers and kmph. For miles, convert km to miles (1 km = 0.621371 miles).

Q2: How do I enter time in minutes?
A: Convert minutes to hours by dividing by 60 (e.g., 45 minutes = 0.75 hours).

Q3: What if I know speed and distance but need time?
A: Rearrange the formula: \( T = \frac{D}{S} \). We may add this calculation option in future.

Q4: Is this average or instantaneous speed?
A: This calculates average speed over the entire distance and time period.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but real-world speed may vary due to stops, traffic, etc.
