Discussion
Ravi walks 12 m towards the west, turns right and walks 5 m, then turns right again and walks 12 m. How far and in which direction is he from his starting point ?
Answer: B
Correct answer: 5 m north
From west, a right turn faces him north; after 5 m, another right turn faces him east. The 12 m west and 12 m east cancel.
\[\text{Net displacement} = 5 \text{ m towards the north}\]
