Do train delhi se mumbai ke liye chalti hai pahli train 2 ghante pahle...
Problem Setup
- Train 1 (First Train) leaves Delhi for Mumbai.
- Departure time: 2 hours before Train 2.
- Speed of Train 1: 40 km/h.
- Train 2 (Second Train) leaves 2 hours after Train 1.
- Speed of Train 2: 60 km/h.
Distance Calculation
1. Distance covered by Train 1 before Train 2 departs:
- Time = 2 hours
- Speed = 40 km/h
- Distance = Speed × Time = 40 km/h × 2h = 80 km
2. Relative speed when both trains are moving towards each other:
- Speed of Train 1 = 40 km/h
- Speed of Train 2 = 60 km/h
- Combined speed = 40 km/h + 60 km/h = 100 km/h
Time to Meet After Train 2 Departs
1. Distance between the two trains when Train 2 starts:
- Distance = Distance covered by Train 1 = 80 km
2. Time taken for both trains to meet:
- Time = Distance / Combined Speed = 80 km / 100 km/h = 0.8 hours
Distance to Meeting Point
1. Distance covered by Train 1 in 0.8 hours:
- Distance = Speed × Time = 40 km/h × 0.8h = 32 km
2. Distance covered by Train 2 in 0.8 hours:
- Distance = Speed × Time = 60 km/h × 0.8h = 48 km
Final Distance from Delhi to Meeting Point
- Total Distance from Delhi to the meeting point:
- Distance covered by Train 1 before Train 2 departs + Distance covered by Train 1 in 0.8 hours
- 80 km + 32 km = 112 km
Conclusion
- Both trains will meet at a distance of 112 km from Delhi.
- Train 1 (First Train) leaves Delhi for Mumbai.
- Departure time: 2 hours before Train 2.
- Speed of Train 1: 40 km/h.
- Train 2 (Second Train) leaves 2 hours after Train 1.
- Speed of Train 2: 60 km/h.
