Answer options

  1. 10 meters
  2. 20 meters
  3. 30 meters
  4. 0 meters

Correct answer and explanation

Correct answer: 10 meters

Explanation: āœ… Correct Answer: A) 10 meters šŸ“š Explanation: She walks 30m North, then 40m East. Her next right turn takes her 20m South, and her final right turn takes her 40m West. Her final Westward movement perfectly cancels out her Eastward movement. Her vertical position is 30m North minus 20m South, leaving her exactly 10 meters North of her starting point.
