Show answer & explanation
Correct answer: C
Key steps:
Walk 50 meters west. Position: 50 meters west of the start.
Turn right (now facing north) and walk 10 meters. Position: 50 meters west and 10 meters north.
Turn right again (now facing east) and walk 20 meters. Position: 30 meters west and 10 meters north (because 50 west then 20 east leaves 30 west).
Turn right once more (now facing south) and walk 10 meters. The 10 m north and 10 m south cancel, leaving position: 30 meters west of the start.
Final answer: 30 meters, West
