1. What is the Miles Per Hour Formula?

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

Purpose: It helps travelers, drivers, and transportation professionals calculate 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 traveled (miles)
• \( T \) — 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 trip planning, fuel estimation, and ensuring compliance with speed limits.

4. Using the Calculator

Tips: Enter the distance in miles and time in hours. For partial hours, use decimals (e.g., 30 minutes = 0.5 hours).

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for kilometers?
A: The formula works the same, but you'll get km/h instead of mph. Make sure all units match.

Q2: How do I convert minutes to hours?
A: Divide minutes by 60 (e.g., 45 minutes = 45/60 = 0.75 hours).

Q3: What if I have seconds?
A: Convert seconds to hours by dividing by 3600 (60 seconds × 60 minutes).

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: Yes, rearrange the formula: \( D = S \times T \) or \( T = \frac{D}{S} \).
