Basic Time-Speed-Distance

Use fundamental formula S = D/T.

When to Use: For any basic TSD calculation.

Step-by-Step Method

  1. Speed = Distance / Time
  2. Distance = Speed × Time
  3. Time = Distance / Speed
  4. Keep units consistent!

Worked Example

Question: A car travels 240 km in 4 hours. Find speed.

  1. Speed = Distance / Time
  2. Speed = 240 / 4 = 60 km/hr

Final Answer: 60 km/hr
