Two trains leave Agra for Calcutta at 9:00 a.m. and 9:30 a.m., respectively, and travel at 240 km/h and 300 km/h, respectively.
How many kilometres from Agra will the two trains meet?
270 km
300 km
600 km
240 km
- The first train leaves Agra at 9:00 a.m. traveling at 240 km/h.
- The second train leaves 30 minutes later at 9:30 a.m. traveling at 300 km/h.
- In 30 minutes, the first train travels 120 km (0.5 hours × 240 km/h).
- The second train starts chasing the first train, closing the distance at a relative speed of 60 km/h (300 km/h - 240 km/h).
- It takes 2 hours (120 km ÷ 60 km/h) for the second train to catch up with the first train.
- During this 2-hour period, both trains travel from Agra:
- The first train covers 480 km (2 hours × 240 km/h).
- The second train covers 600 km (2 hours × 300 km/h).
- So, the trains meet 600 km from Agra.
Option 3: 600 km is the correct answer.
