Peter is facing North. He turns to his right and walks 20 m, and then turns to his left and walks 25 m. He then turns to his right and walks 25 m. Next, he turns to his right and walks 50 m. Finally, he turns to his right and walks 30 m. In which direction is he now from the starting point?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → South-East
A right turn moves the facing direction one step clockwise and a left turn one step anticlockwise (North → East → South → West → North). Track the facing direction after every turn.
Facing North, turns right: now facing East, 20 m: 20 m east of the start
Turns left, now facing North, 25 m: 20 m east, 25 m north
Turns right, now facing East, 25 m: \(20+25=45\) m east, 25 m north
Turns right, now facing South, 50 m: \(50-25=25\) m south, 45 m east
Turns right, now facing West, 30 m: \(45-30=15\) m east, 25 m south
He is south and east of the start
He is South-East of the starting point.
