1. Basic Formula
Speed tells how much distance is covered in a unit of time.
Question: A car covers 180 km in 3 hours
- Identify the given values carefully.
- Write the required formula.
- Substitute the values step by step.
- Simplify the calculation.
- Answer: Speed=180/3=60 km/h.
Apply the same concept to a similar SSC GD question and keep units consistent.
- Read the question.
- Write the known values.
- Choose the correct formula.
- Calculate carefully.
- Box the final answer.
Check your answer using the reverse calculation wherever possible.
- Write the required relation.
- Substitute the values.
- Simplify each step.
- Check the result.
- Final: The answer follows from the formula above.
2. Unit Conversion
Convert km/h to m/s by multiplying by 5/18; convert m/s to km/h by multiplying by 18/5.
Question: 72 km/h to m/s
- Identify the given values carefully.
- Write the required formula.
- Substitute the values step by step.
- Simplify the calculation.
- Answer: 72×5/18=20 m/s.

- Final: The answer follows from the formula above.
3. Average Speed
Average speed is total distance divided by total time, not the simple average unless distances/times justify it.
Question: 60 km in 2 h and 40 km in 1 h
- Identify the given values carefully.
- Write the required formula.
- Substitute the values step by step.
- Simplify the calculation.
- Answer: Average=100/3=33.33 km/h.

- Write the required relation.
- Substitute the values.
- Simplify each step.
- Check the result.
- Final: The answer follows from the formula above.
4. Relative Speed
For opposite directions add speeds; for same direction subtract speeds.
Question: Two trains at 50 and 70 km/h opposite
- Identify the given values carefully.
- Write the required formula.
- Substitute the values step by step.
- Simplify the calculation.
- Answer: Relative speed=120 km/h.
