- The distance between stations 'A' and 'B' is 494 km.

- Train 1 leaves 'A' at 3 p.m., travelling towards 'B' at 83 km/h.

- By 4 p.m., Train 1 has travelled 83 km (1 hour * 83 km/h).

- Train 2 starts from 'B' at 4 p.m., moving towards 'A' at 54 km/h.

- Now, both trains are 411 km apart (494 km - 83 km).

- Their combined speed is 137 km/h (83 km/h + 54 km/h).

- Time taken to meet: 411 km / 137 km/h = 3 hours.

- They meet 3 hours after 4 p.m., at 7 p.m.
