Difficulty: Medium
Correct Answer: West
Explanation:
Introduction / Context:
This is a direction-sense puzzle about relative placement of three players A, B, and C on a plane. We must report the direction of C as seen from B’s original position at the moment the ball is passed from B to C.
Given Data / Assumptions:
Concept / Approach:
Use a coordinate frame. Place B at the origin for convenience. Directions: east = +x, north = +y. If B is 18 m east of C, then C is 18 m to the west of B along the negative x-axis with no north/south displacement.
Step-by-Step Solution:
Verification / Alternative check:
Any north/south offset would have appeared as “north of” or “south of.” Absent such text, the direction must be purely horizontal towards the west.
Why Other Options Are Wrong:
Common Pitfalls:
Trying to force all three relational lines into a single consistent triangle; the question only needs B→C direction, which is unambiguous.
Final Answer:
West
