• A. 15 km South
• B. 10 km North
• C. 15 km East
• D. 15 km North
• E. 10 km East

Hint:

Sketching a quick directional cross and plotting the movements ensures you don't confuse "left/right" with "East/West."

Answer 1

The Correct Option is D

Step 1: Analyse options.
- Initial: 10 km North. - Turn Left: 4 km West. - Turn Right: 5 km North. - Turn Right: 4 km East. - Net Horizontal: $4\text{ (West)} - 4\text{ (East)} = 0$. - Net Vertical: $10\text{ (North)} + 5\text{ (North)} = 15\text{ km North}$.
Step 2: Conclusion.
She is 15 km North from the start. Final Answer: (d) 15 km North
