Difficulty: Medium
Correct Answer: West
Explanation:
Introduction / Context:
This itinerary mixes several right/left turns. We compute the final coordinates and then determine the direction from the origin to the final point.
Given Data / Assumptions:
Concept / Approach:
Use coordinates with origin at the start. Sum each axis displacement and interpret the final vector.
Step-by-Step Solution:
After first three legs: (20, −40).After West 40: (−20, −40).After North 40: (−20, 0).Relative to the origin, the point is 20 m West.
Verification / Alternative check:
Vertical displacement cancels to zero; only a 20 m West offset remains.
Why Other Options Are Wrong:
North/South/East do not match the computed negative x (West) position.
Common Pitfalls:
Misapplying the last “right,” which is from West to North before moving 40 m.
Final Answer:
West
