Quantitative Aptitude - Problems on Trains
Solve problems involving trains crossing platforms, signals, or each other using relative speed.
1. Concepts
Use relative speed for moving objects: same direction → subtract; opposite direction → add.
2. Basic Formula
Time to cross = Length to cross / Relative speed. Convert speed into same unit as length.
3. Quick Tips
- Use combined lengths when crossing each other.
- Convert speed from km/h to m/s when needed.
- Sketch the scenario to clarify what is crossed.
4. Common Errors
- Forgetting to convert speed units.
- Using wrong relative speed formula.
5. Revision Checklist
- Practice crossing, overtaking and combined length problems.
Summary: Convert speed units, use relative speed, and divide by total length to find time with ease.
