Difficulty: Easy
Correct Answer: 1 KM
Explanation:
Introduction / Context:
The path forms a near-rectangle with one side longer on the final East leg. We compute net displacements on each axis and then the straight-line distance to the origin.
Given Data / Assumptions:
Concept / Approach:
End point: (1, 0). Distance to origin is simply the absolute x-offset.
Step-by-Step Solution:
Final coordinates: (1, 0).Distance = sqrt(1^2 + 0^2) = 1 km.
Verification / Alternative check:
North/South cancel; net East = 1 km.
Why Other Options Are Wrong:
2/3/5 km do not reflect the computed net offset.
Common Pitfalls:
Forgetting that the North and South legs cancel exactly.
Final Answer:
1 KM
