Aditi walks 16 meters towards the west, then turns to her right and walks 16 meters and then turns to her left and walks 12 meters. Again turning to her left, she walks 16 meters. What is the shortest distance between her starting point and her present position?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 28m
Each turn is taken from the direction Aditi is facing at that moment:
She walks 16 m West, so she faces West
Facing West, a right turn is North: 16 m North
Facing North, a left turn is West: 12 m West
Facing West, a left turn is South: 16 m South
The 16 m North and 16 m South cancel out, so she ends on the same East-West line as the start, \(16+12=28\) m to its West.
