A strict boat went along the river at a speed of 16 km / h, and against the current at a speed of 14 km / h.

A strict boat went along the river at a speed of 16 km / h, and against the current at a speed of 14 km / h. Find the speed of the river.

1) Let’s make the equation:
Let the speed of a strict boat going downstream be (16 – x) km / h, then the speed of a strict boat going against the current is (14 + x) km / h. We get the equation:
16 – x = 14 + x.
2) Let’s solve this equation:
-x – x = 14 – 16.
-2x = -2.
2x = 2.
x = 2/2.
x = 1km / h.
Answer: the speed of the current is 1 kilometer per hour.
