Answer 2

Calculating the Boat's Speed

To find the speed of the boat in still water, we can use the formula: Boat's speed in still water = (Speed upstream + Speed downstream) / 2

Given: - Speed upstream = 6 km/h (against the current) - Speed downstream = 5 km/h (with the current) - Speed of the current = 3 km/h

Using the formula: Boat's speed in still water = (6 + 5) / 2 = 11 / 2 = 5.5 km/h

So, the speed of the boat in still water is 5.5 km/h.
