Robin walked 30 meters towards North, took a left turn and walked 15 meters. He again took a left turn and walked 30 meters. How far and in which direction is he from the starting point?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 15 meters West
A left turn while walking north points a person west, and a left turn while walking west points him south.
30 m north
Left turn (now facing west): 15 m west
Left turn (now facing south): 30 m south, which cancels the 30 m north
Only the 15 m west is left, so Robin is 15 m west of the starting point.
