Difficulty: Easy
Correct Answer: 24
Explanation:
Introduction / Context:
We track axis-aligned moves and compute the straight-line (Euclidean) distance between the start and end points. Right/left are relative to current facing.
Given Data / Assumptions:
Concept / Approach:
Use coordinates with start at (0,0). West decreases x; East increases x; North increases y; South decreases y.
Step-by-Step Solution:
After 14 W: (−14, 0).Right to North, +14: (−14, 14).Left to West, +10: (−24, 14).Left to South, +14: (−24, 0).Distance from (0,0) to (−24,0) = 24 m.
Verification / Alternative check:
The y ends back at 0, so only x offset matters; tallying westward distances (14 + 10) minus any east returns confirms 24 m.
Why Other Options Are Wrong:
10, 28, 38 m do not match the computed coordinate difference.
Common Pitfalls:
Misreading left/right relative to current facing rather than absolute compass directions.
Final Answer:
24
