The own speed of the motor ship is 53.2 km h. The speed of the motor ship against the current is 50.5 km h.

The own speed of the motor ship is 53.2 km h. The speed of the motor ship against the current is 50.5 km h. Find the speed of the thermal fluid along the rivers.

First you need to find the speed of the river.
Since we know the own speed of the motor ship and its speed against the current, for this we subtract the speed of the river from its own speed.
We get:
53.2 – 50.5 = 2.7 km / h.
The downstream speed of a river is the sum of its own speed and the speed of the current.
The result will be:
53.2 + 2.7 = 55.9 km / h.
Answer: The speed of the ship along the river is 55.9 km / h.
