Answer 2

Calculating River Current Speed

To find the speed of the river current, we can use the formula:

Boat's speed in still water = (Boat's speed with the current + Boat's speed against the current) / 2 River's current speed = (Boat's speed with the current - Boat's speed in still water)

Given: - Boat's speed with the current = 25 1/3 km/h - Boat's speed against the current = 23 1/3 km/h

Let's calculate the boat's speed in still water first.

Boat's speed in still water = (25 1/3 + 23 1/3) / 2 = (76/3 + 70/3) / 2 = (146/3) / 2 = 73/3 = 24 1/3 km/h

Now, we can calculate the river's current speed using the boat's speed in still water.

River's current speed = (25 1/3 - 24 1/3) = 1 km/h

Therefore, the speed of the river's current is 1 km/h.
