1. What is a Speed Calculator?

Definition: This calculator computes speed in miles 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 (miles per hour)
• \( D \) — Distance (miles)
• \( T \) — Time (hours)

Explanation: The distance traveled is divided by the time taken to complete the journey.

3. Importance of Speed Calculation

Details: Accurate speed calculation helps in trip planning, fuel efficiency estimation, and maintaining safe travel speeds.

4. Using the Calculator

Tips: Enter the distance in miles 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 kilometers instead of miles?
A: No, 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 by dividing by 60 (e.g., 45 minutes = 0.75 hours).

Q3: What if my time includes hours and minutes?
A: Convert to decimal hours (e.g., 2 hours 30 minutes = 2.5 hours).

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

Q5: Can I calculate distance or time if I know speed?
A: No, this calculator only computes speed. You would need to rearrange the formula for other calculations.
