- The speed of the boat in still water is given as 10 km/h.

- The speed of the stream is 2 km/h.

- When going upstream, the effective speed of the boat is reduced due to the stream. Thus, upstream speed = 10 km/h - 2 km/h = 8 km/h.

- For 4 hours of rowing upstream, the distance is calculated as: 8 km/h * 4 h = 32 km.

- When going downstream, the effective speed of the boat is increased by the stream. Thus, downstream speed = 10 km/h + 2 km/h = 12 km/h.

- For 3 hours of rowing downstream, the distance is calculated as: 12 km/h * 3 h = 36 km.

- Combining both distances, the total distance is: 32 km + 36 km = 68 km.

- Option 4 – 68 km is the correct answer.
