1. What is the Speed Distance Time Equation?

Definition: These equations describe the relationship between speed, distance traveled, and time taken.

Purpose: Used in physics, transportation, sports, and many other fields to calculate one variable when the other two are known.

2. How Do the Equations Work?

The three interrelated formulas:

\[ d = v \times t \] \[ v = \frac{d}{t} \] \[ t = \frac{d}{v} \]

Where:

\( d \) — Distance (meters)
\( v \) — Speed or velocity (meters/second)
\( t \) — Time (seconds)

Explanation: These equations show that distance equals speed multiplied by time, speed equals distance divided by time, and time equals distance divided by speed.

3. Importance of Speed Distance Time Calculations

Details: Essential for journey planning, physics problems, vehicle performance analysis, and many real-world applications involving motion.

4. Using the Calculator

Tips: Enter any two known values (leave one field empty) to calculate the missing value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: The calculator uses meters (m) for distance, meters/second (m/s) for speed, and seconds (s) for time. Convert your units accordingly.

Q2: Can I use this for average speed calculations?
A: Yes, the equations work for average speed when distance is the total distance and time is the total time taken.

Q3: How do I convert km/h to m/s?
A: Multiply km/h by 0.2778 to get m/s (or divide by 3.6).

Q4: What if I get a division by zero error?
A: Time cannot be zero when calculating speed, and speed cannot be zero when calculating time.

Q5: Can this be used for acceleration problems?
A: No, these equations are for constant speed only. For acceleration, different equations are needed.
