Difficulty: Medium
Correct Answer: East
Explanation:
Introduction / Context:We must find the final position relative to the origin after several orthogonal moves with alternating turns.
Given Data / Assumptions:
Concept / Approach:Sum x and y components.
Step-by-Step Solution:
x: +40 + 20 − 20 = +40.y: +25 − 45 + 20 = 0.Net = (40, 0) ⇒ due East.Verification / Alternative check:Sketching quickly shows the path ends directly to the right of the start on the same horizontal line.
Why Other Options Are Wrong:
Common Pitfalls:Mistaking the final left from North as “West then 20” (it is West indeed, already included in the x total).
Final Answer:East
