Show answer & explanation
Correct answer: B
Key insight: reverse the turns from the final direction.
Final facing: North.
Since the last move was a left turn to end facing North, you were facing East just before that left turn.
That East direction came from making a right turn earlier, so the initial direction must have been North (turning right from North gives East).
The distances (6 km, 2 km, 10 km) do not affect the directions, only the turns do.
Answer: You started your journey facing North.
