A ship sails on a river. After 6 hours, it returns to its starting point, having covered a distance of 36 km according to the map (naturally, the ship had to move in one direction and then in the opposite direction).

What is the speed of the ship if we assume that it did not spend any time turning around and the speed of the river current is $3 \mathrm{~km} / \mathrm{h}$?
