A man leaves from his home. He first walks 40 meters in north-west direction and then 40 meters in south-west direction. Next he walks 40 meters in south-east direction. Finally, he turns towards his house. In which direction is he moving?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → North-east
The three walks are of the same length, 40 m, and each turns through a right angle (north-west, south-west, south-east), so they form three sides of a square. The fourth side, back to the house, runs opposite to the second walk: the reverse of south-west is north-east.
