Question

Sapna travels 10 km North, turns left 4 km, turns right 5 km, then turns right 4 km. How far is she from the starting point and in which direction?

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

Hint:

Opposite directions (East vs West, North vs South) can be treated as positive and negative values to quickly find the net displacement.

Answer 1

The Correct Option is D

Step 1: Analyse options.
- Sapna moves 10 km North. - Turns left (West) for 4 km. - Turns right (North) for 5 km. - Turns right (East) for 4 km. - The 4 km West and 4 km East cancel each other out. - Total North distance = $10 + 5 = 15 \text{ km}$.
Step 2: Conclusion.
She is 15 km North from the starting point. Final Answer: (d) 15 km North
