Answer
Correct Answer: South
Explanation
Introduction / Context:We compute the net displacement and then state the bearing from the starting point.
Given Data / Assumptions:
- N 8 → E 12 → N 7 → S 24 → W 12.
Concept / Approach:Sum x and y components independently.
Step-by-Step Solution:
x: +12 − 12 = 0.y: +8 + 7 − 24 = −9.Net = (0, −9) ⇒ due South of the start.Verification / Alternative check:Horizontal movements cancel; vertical net is 9 km south.
Why Other Options Are Wrong:
- North/East/West imply different nonzero components not present.
Common Pitfalls:Forgetting to subtract the large southward leg from the total northward movement.
Final Answer:South
