- The two trains are moving towards each other with speeds of 70 km/h and 85 km/h.

- Convert these speeds to meters per second:

- 70 km/h = 70 * 1000/3600 = 19.44 m/s

- 85 km/h = 85 * 1000/3600 = 23.61 m/s

- Their combined speed is 19.44 m/s + 23.61 m/s = 43.05 m/s.

- The total length of both trains together is 210 m + 255 m = 465 m.

- Time to cross each other is total length divided by relative speed:

- 465 m / 43.05 m/s = 10.8 seconds

- Option 3: 10.8 seconds is correct.
