| Let’s find the speed of the river. To do this, subtract the speed of the boat against the river flow – 14.8 kilometers per hour from the speed of the boat along the river – 19.2 kilometers per hour:

19.2 – 14.8 = 4.4 kilometers per hour.

The speed of the boat downstream of the river differs from the speed of the boat upstream of the river by 4.4 kilometers per hour.

Let’s calculate the speed of the river. Divide the resulting figure by 2:

4.4: 2 = 2.2 kilometers per hour.

The speed of the river is 2.2 kilometers per hour.

Answer: the speed of the river is 2.2 kilometers per hour.
