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.
