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 solution of the problem:
1. To solve the problem, we need to find our own speed of the boat.
18-1.8 = 16.2 kilometers per hour
2. In the second step, we will determine at what speed the boat goes against the current per hour.
16.2-1.8 = 14.4 kilometers per hour
Answer: The speed of the boat against the current of the river is fourteen kilometers and four hundred meters per hour.
