DWest
Correct Answer: NorthYour Answer: C
Explanation
Step 1: The stated time places the Sun in the East. | Step 2: A shadow forms opposite the Sun, so it points West. | Step 3: Use the stated left/right or facing relation; the required direction is North. | Answer: Option C — North.
Important Notes
- Draw a north arrow before solving and take East as positive x, West as negative x, North as positive y, and South as negative y. |
- Apply every turn from the person's current facing direction. A right turn changes direction clockwise; a left turn changes it anticlockwise. |
- Combine opposite movements before calculating distance: cancel East with West and North with South. |
- Decide the final direction from the signs of the remaining horizontal and vertical displacements. For example, positive x and negative y indicate South-East. |
