Given Information:
- Speed of the stream = 3 km/hr
- Time taken downstream = 4 hours
- Time taken upstream = 5 hours

Let's assume:
- Speed of the motorboat in still water = x km/hr

Concept:
- Speed downstream = Speed of motorboat + Speed of stream
- Speed upstream = Speed of motorboat - Speed of stream

Calculations:
- Let's calculate the speed of the motorboat downstream:
- Speed downstream = x + 3 km/hr
- Distance = Speed x Time
- Distance = (x + 3) x 4
- Let's calculate the speed of the motorboat upstream:
- Speed upstream = x - 3 km/hr
- Distance = Speed x Time
- Distance = (x - 3) x 5
- Since the distance covered in both directions is the same:
- (x + 3) x 4 = (x - 3) x 5
- 4x + 12 = 5x - 15
- x = 27 km/hr

Conclusion:
- Therefore, the speed of the motorboat in still water is 27 km/hr.
