Nikhil walks 16 m towards the North from his school gate, then turns right and walks 12 m. In which direction must he now walk to go straight back to the school gate?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → South-West
A right turn moves the facing direction one step clockwise (North → East). Find where he ends up from the gate; the way back is the opposite of that.
Facing North, 16 m: 16 m north of the gate
Turns right, now facing East, 12 m: 16 m north, 12 m east
He is north and east (North-East) of the gate, so to reach it he must move south and west at the same time
He must walk towards the South-West.
