⚡ Speed Distance Time Calculator
Solve physics problems with automatic unit conversions (km/h, mph, m/s) and step-by-step solutions. Perfect for students and professionals.
📚 Understanding the Speed Distance Time Formula
The relationship between speed, distance, and time is fundamental in physics. The formula triangle is a handy way to remember the three equations:
- Speed = Distance ÷ Time (How fast something is moving)
- Distance = Speed × Time (How far something has traveled)
- Time = Distance ÷ Speed (How long it takes to travel)
📐 Unit Conversion Factors
🏃 Speed Units
- 1 km/h = 0.27778 m/s
- 1 mph = 0.44704 m/s
- 1 knot = 0.51444 m/s
📏 Distance Units
- 1 km = 1000 m
- 1 mile = 1609.34 m
- 1 foot = 0.3048 m
⏱️ Time Units
- 1 hour = 3600 s
- 1 minute = 60 s
❓ Frequently Asked Questions
How to calculate average speed?
Total Average Speed is always Total Distance divided by Total Time. Do not simply average the speeds of different legs of a journey.
How do I convert km/h to m/s?
Divide the speed in km/h by 3.6 to get m/s. For example, 100 km/h ÷ 3.6 = 27.78 m/s.
What is the formula triangle?
The formula triangle places Distance (D) at the top and Speed (S) and Time (T) at the bottom. To find one variable, cover it up: S = D/T, T = D/S, D = S × T.
