Starting from the school gate, Imran walks 25 m towards the North. He turns right and walks 18 m, turns right again and walks 25 m, and then turns left and walks 7 m. How far and in which direction is he from the school gate?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 25 m East
A right turn moves the facing direction one step clockwise (North → East → South) and a left turn one step anticlockwise (South → East). Track the facing direction after every turn and keep a running total of the distance from the gate.
Facing North, 25 m: 25 m north of the gate
Turns right, now facing East, 18 m: 25 m north, 18 m east
Turns right, now facing South, 25 m: \(25-25=0\) m north, 18 m east
Turns left, now facing East, 7 m: \(18+7=25\) m east
He is 25 m East of the school gate.
