Let the two village women start from the same point A. The first woman (by black) walks 1 km South, then turns to her right and walks 6 km westwards to reach her house C. Also, the second woman (in red) walks 5 km West to Z, then she turns North and walks 4 km to reach point Y, then she turns to her left and walks 1 km to reach her house X.
∴ The second woman's house is 5 km north with respect to the first woman's house.
