Rasik walked 20 m towards north. Then he turned right and walks 30 m. Then he turns right and walks 35 m. Then he turns left and walks 15 m. Finally he turns left and walks 15 m. In which direction and how many metres is he from the starting position?
Answer: D
Correct answer: 45 m East
Adding the legs: north 20, then east 30, then south 35, then east 15, then north 15. The northward moves come to \( 20 - 35 + 15 = 0 \) and the eastward to \( 30 + 15 = 45 \). So he finishes 45 m east of his starting point.
