| **The speed of the boat against the stream of the river is 19.2 km / h, the speed of the current is 1.8 km / h. Find the entire path covered by the boat, if it goes 5 hours downstream and 3 hours upstream?**

Find the doubled value of the river flow velocity.

1.8 * 2 = 3.6 km / h.

Determine the speed of the boat downstream.

Add the obtained value to the speed upstream.

Will be:

19.2 + 3.6 = 22.8 km / h.

Find the distance that the boat has traveled in each direction.

To do this, we multiply the corresponding speed by the time of movement.

22.8 * 5 = 114 km (the boat went downstream).

19.2 * 3 = 57.6 km (the boat passed against the stream).

In this case, the boat sailed in total:

114 + 57.6 = 171.6 km.

Answer: 171.6 km.
