# The motor ship sails along the river at a speed of 32.4 km / h. The speed of the river is 2.8 km / h.

**The motor ship sails along the river at a speed of 32.4 km / h. The speed of the river is 2.8 km / h. Find your own speed of the ship and its speed upstream of the river.**

Let us find the value of the own speed of this motor ship, for this we need the value of the speed along the river flow of the given motor ship to subtract the value of the speed of the river flow:

32.4 – 2.8 = 29.6 km / h – this is the value of the own speed of this motor ship;

Let’s find the value of the speed against the current of a given speed, for this we need the value of its own speed to subtract the value of the speed of the river flow:

29.6 – 2.8 = 26.8 km / h – this is the value against the river flow of this motor ship.

Answer: 29.6 km / h is the value of the own speed of this motor ship; 26.8 km / h is such a value against the river flow of this motor ship.
