Find the speed of the boat upstream of the river if the current speed is 1.8 km / h and the speed

Find the speed of the boat upstream of the river if the current speed is 1.8 km / h and the speed of the boat downstream is 18 km / h.

The current speed is 1.8 km / h.
Downstream speed – 18 km / h.
What is the speed of the boat against the current?
1) 18-1.8 = 16.2 (km / h) speed of the boat.
2) 16.2-1.8 = 14.4 (km / h) speed upstream.
The speed against the current is 14.4 km / h.

If the boat goes with the current, then its speed increases by the speed of the current. If the boat goes against the current, its speed is reduced by the speed of the current.
