Explanation

Let's analyze Gaurav's movements step by step:

  1. Gaurav walks 20 metres North.
  2. Turns left (now facing West) and walks 40 metres.
  3. Turns left again (now facing South) and walks 20 metres.
  4. Turns right (now facing West) and walks 20 metres.

Find the final position relative to the starting point:

  • North-South Movement:
    • Moves 20m North initially.
    • Moves 20m South later.
    • Net vertical movement = 20 - 20 = 0m (back to the original latitude).
  • East-West Movement:
    • Moves 40m West initially.
    • Moves 20m more West later.
    • Net horizontal movement = 40 + 20 = 60m West.

Final Position:

  • Gaurav is 60 metres to the West of his starting point.

Correct Answer:

D: 60 metres
