Show answer & explanation
Correct answer: D
Answer: 50 m
Reasoning:
Start: Rakesh walks 30 m south.
Then he turns right (facing west) and walks 30 m west.
Then he turns left (now facing south) and walks 20 m south.
Finally he turns left (facing east) and walks 30 m east.
Combine components:
Vertical (north–south): 30 m south + 20 m south = 50 m south.
Horizontal (east–west): 30 m west + 30 m east = 0 (they cancel).
Therefore the net displacement from the starting point is 50 m south, so the distance from the initial position is 50 m.
