A fast flowing stream is called a rapid. Rapids are where the water flows downhill very fast and over underwater obstacles.
Well....... It depends. If the river is really big and wide, and there are hardly any plants growing in it, and there are no rocks and the river is on a plain, then it will probably flow really fast. If the river is atiny little stream in the mountains, then it will probably flow slower. It all depends on the river
