- The total distance between stations A and B is 800 km.

- Train X starts from A moving towards B at a speed of 40 km/h.

- Train Y starts from B moving towards A at a speed of 60 km/h.

- The trains are moving towards each other, so we can add their speeds for relative speed calculation.

- Relative speed = 40 km/h + 60 km/h = 100 km/h.

- To find when they will meet, use the formula: Distance = Speed × Time.

- They need to cover 800 km combined, so 800 km = 100 km/h × Time.

- Time = 800/100 = 8 hours.

- In 8 hours, Train X (traveling from A) will cover: 40 km/h × 8 hours = 320 km.

Option 2: 320 km is indeed correct.
