Gaurav comes out of the back door of his house whose main door is facing north and walks 25m straight, then he turns left and walks 36m, he again turns left and walks 47m. He again turns left and walks 36m. How far and in which direction is he from his house now?
Explanation:
Main door faces north, so back door faces south. Path: 25 m south, left (east) 36 m, left (north) 47 m, left (west) 36 m. Net displacement: north 47 - south 25 = 22 m north; east 36 - west 36 = 0. So he is 22 m north of his house.
Vinay walks 6 meters towards north. Then he takes a 90° right turn and walks 9 metres. Then he takes a 135° left turn and walks 12 metres. Which direction is he facing now?
A person walks 5 m towards north. He turns left and walks 10 m. Then turns right and walks 20 m. Then turns right and walks 10 m. At what distance is he from the starting point?
