The speed of the boat against the current is 11.3 km / h. The current speed is 3.9 km / h.

The speed of the boat against the current is 11.3 km / h. The current speed is 3.9 km / h. Find your own speed of the boat and its speed with the current.

1. Let’s calculate the independent speed of a sailing boat, if it
moved in still water in km / h.
11.3 + 3.9 = 15.2 (km / h);
2. Based on the conditions of the problem, we find the digital value of the speed
the movement of our boat along the river in km / h.
15.2 + 3.9 = 19.1 (km / h);
Answer: The independent speed of the boat is
15, 2 kilometers per hour, the speed of our boat
the movement of water in the river is 19.1 kilometers per hour
