Initial Direction of the Boy
To determine the initial direction the boy started walking, let’s break down his movements step by step.
Step-by-Step Movement Analysis
1. Initial Direction:
- The boy walks 5 km in an initial direction. Let’s assume he starts walking North.
2. First Turn:
- After walking North, he takes a left turn. A left turn from North leads him West.
- He then walks 5 km West.
3. Second Turn:
- He takes another left turn. A left turn from West leads him South.
- He walks 5 km South.
4. Third Turn:
- Finally, he takes a right turn. A right turn from South leads him West.
- He walks 5 km West again.
Final Position Evaluation
- After completing the movements:
- He started at a point (let's call it Point A).
- After walking North, he reaches Point B.
- From Point B, he walks West to Point C.
- From Point C, he walks South to Point D.
- Lastly, he walks West to Point E.
- His final position (Point E) is directly West of his starting point (Point A).
Shadow Direction Analysis
- Since the sun rises in the East, at that time of the day, the boy’s shadow will be cast in the opposite direction, which is West.
- As he sees his shadow in front of him, it confirms that he is facing East.
Conclusion
- Thus, if he sees his shadow in front of him after all these movements, he must have started walking in the North direction.
