Answer 2

Calculating Boat's Speed and River's Current

To find the boat's speed and the river's current, we can use the following information:

- The boat's speed downstream (with the current) is 10 km/h. - The boat's speed upstream (against the current) is 6 km/h.

Let's calculate the boat's speed and the river's current using this information.

Boat's Speed Calculation

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

Using the given values: Boat's Speed = (10 km/h + 6 km/h) / 2 = 16 km/h / 2 = 8 km/h.

So, the boat's speed is 8 km/h.

River's Current Calculation

To find the river's current, we can use the formula: River's Current = (Speed downstream - Boat's Speed).

Using the given values: River's Current = (10 km/h - 8 km/h) = 2 km/h.

So, the river's current is 2 km/h.

Therefore, the boat's speed is 8 km/h and the river's current is 2 km/h.
