Difficulty: Easy
Correct Answer: West
Explanation:
Introduction / Context:A standard grid-walk with cardinal legs. We must identify the final location relative to the origin (A).
Given Data / Assumptions:
Concept / Approach:Sum x and y displacements separately to get E’s coordinates relative to A.
Step-by-Step Solution:
Net x = +10 − 12 = −2 (2 km West).Net y = +3 − 3 = 0.Therefore, E is due West of A.Verification / Alternative check:Drawing a quick rectangle shows overshoot by 2 km to the west after returning south.
Why Other Options Are Wrong:
Common Pitfalls:Losing track of signs during the west leg; keep axes consistent.
Final Answer:West
