About Time-Speed-Distance
Time, Speed, and Distance (TSD) is a high-weightage topic in almost every aptitude exam. The core relationship is Speed = Distance ÷ Time. From this, you can derive Distance = Speed × Time and Time = Distance ÷ Speed. Key problem types include: average speed calculations (especially when the same distance is covered at different speeds), relative speed (objects moving towards or away from each other), train problems (crossing platforms, poles, or other trains), and boat-stream problems. Unit conversion between km/hr and m/s is critical — multiply by 5/18 to go from km/hr to m/s. The solved questions below cover all these patterns.
Key Takeaways
- Always convert to consistent units before solving (km to m, hours to seconds).
- Average speed ≠ average of speeds. Use Total Distance ÷ Total Time.
- For train crossing a platform: Distance = Train length + Platform length.
- Relative speed when moving towards each other: add. Same direction: subtract.
Frequently Asked Questions
How do I convert km/hr to m/s?
Multiply by 5/18. For example, 72 km/hr = 72 × 5/18 = 20 m/s. To convert m/s to km/hr, multiply by 18/5.
How do I calculate average speed?
Average Speed = Total Distance ÷ Total Time. Never take the arithmetic mean of speeds. For two equal distances covered at different speeds: Average = (2 × S1 × S2) ÷ (S1 + S2).
How do relative speed problems work?
When objects move towards each other: Relative speed = S1 + S2. When moving in the same direction: Relative speed = |S1 - S2|. Time to meet/cross = Distance ÷ Relative Speed.
