Solution (By JKExamLibrary)
Path: North 40, left (west) 75, right (north) 30, right (east) 75. She was running east at the end.
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.
