Answer 2

Calculation of the Boat's Speed

To find the boat's own speed, we need to consider the speed of the boat relative to the water. Let's assume the speed of the boat in still water is represented by x km/h.

When the boat is moving with the current of the river, its effective speed increases. In this case, the boat's speed is given as 24 km/h.

When the boat is moving against the current of the river, its effective speed decreases. In this case, the boat's speed is given as 20 km/h.

To find the boat's own speed, we can use the following equation:

Boat's speed with the current - Boat's speed against the current = Boat's own speed

Substituting the given values, we have:

24 km/h - 20 km/h = 4 km/h

Therefore, the boat's own speed is 4 km/h.
