1. What is the Speed-Distance-Time Equation?

Definition: This equation calculates speed by dividing distance traveled by time taken.

Purpose: It helps in physics, engineering, and everyday situations to determine speed when distance and time are known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( v \) — Speed (meters/second)
• \( d \) — Distance traveled (meters)
• \( t \) — Time taken (seconds)

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

3. Importance of Speed Calculation

Details: Understanding speed is fundamental in physics, transportation planning, sports science, and many engineering applications.

4. Using the Calculator

Tips: Enter the distance in meters and time in seconds. Both values must be > 0. The result is given in meters per second (m/s).

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units?
A: Yes, but ensure consistency (e.g., km and hours will give km/h). This calculator uses meters and seconds for m/s.

Q2: What if I know speed and need distance or time?
A: The formula can be rearranged: \( d = v \times t \) or \( t = \frac{d}{v} \).

Q3: Does this calculate average or instantaneous speed?
A: This calculates average speed over the given distance and time period.

Q4: How accurate is this calculation?
A: It's mathematically precise for the inputs given, assuming constant speed.

Q5: What's a typical walking speed in m/s?
A: About 1.4 m/s (5 km/h) for average adult walking pace.
