Srinija walked 9 km west from her home, then turned south and walked 11 km. Then she walked 13 km towards east and finally 4 km towards west. Now at what distance is Srinija from its initial position?
A boy facing east turns to his right and walks 20 metres. Then he turns to his left and walks 15 metres. After this he walks 25 meters while facing west. He then turns to his right and walks 20 metres. At what distance is he now from his initial position?
Explanation:
He turns right (facing South) and walks 20 m. Turns left (facing East) and walks 15 m. Faces West and walks 25 m, making him 10 m West of his starting longitude (15 - 25 = -10). He turns right (North) and walks 20 m, returning to his starting latitude. He is 10 m West of the start.
