A man can row at 5 kmph in still water

A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 2 hour to row to a place and come back, how far is the place?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
