A girl walks 100 m straight from her home, to go to the market during her morning walk. Then she turns left for 60 m, the 85 m turning her right and then again turns right for 60 m, she can see her shadow now. Therefore, in which direction is the entry gate of her house facing and what is the shortest distance from her current location to the home ?
