-

-
CWest
-
DSouth
-
ENone of these
Answer
Correct Answer: East
Explanation
Introduction / Context:The problem asks only for the final facing direction, not the final location. That lets us ignore distances for orientation and focus purely on left/right turns from the current heading.
Given Data / Assumptions:
- Start heading: East (first leg).
- Turn right once → heading becomes South.
- Turn left once → heading becomes East again.
- Distances (45, 65, 33 km) do not affect facing, only the turns do.
Concept / Approach:For orientation-only questions, apply each turn relative to the present heading. Right from East is South; left from South is East.
Step-by-Step Solution:Initial: East.Right turn → South.Left turn → East.Final facing = East.
Verification / Alternative check:Sketch a simple compass and rotate 90° at each instruction to confirm.
Why Other Options Are Wrong:North/West/South do not match the left/right sequence applied from East.
Common Pitfalls:Letting distances bias orientation; distances do not change facing.
Final Answer:East
