The speed of the ship along the river is 37.6 km / h Find your own speed of the ship and its speed upstream if the speed of the river is 3.9 km / h
The speed of the ship along the river is the sum of the speed of the ship and the speed of the river.
Let’s find our own speed of the ship. Let us subtract the speed of the river flow from the speed of the motor ship along the river.
37.6 – 3.9 = 33.7 km / h.
The speed of the motor ship against the current is equal to the difference between the own speed of the motor ship and the speed of the current. Let’s find her.
33.7 – 3.9 = 29.8 km / h.
Answer: the own speed of the motor ship is 33.7 km / h, its speed against the current is 29.8 km / h.
