Explanation:

- The boat’s speed in still water is 7 km/h.
- The stream’s speed is 3 km/h.
- *Upstream*, the boat's effective speed = 7 km/h - 3 km/h = 4 km/h.
- *Downstream*, the boat's effective speed = 7 km/h + 3 km/h = 10 km/h.
- Time to travel 60 km upstream = Distance / Speed = 60 km / 4 km/h = 15 hours.
- Time to travel 60 km downstream = 60 km / 10 km/h = 6 hours.
- Total time = 15 hours + 6 hours = 21 hours.

**Correct Answer:** Option 3, 21 hours. ✅
