A man drives 20 km towards the East and turns to the right-hand side and takes a drive of another 3 km. He then drives towards the West (turning to his right) another 3 km. He then turns to his left and walks another 2 km. Afterward, he turns to his right and travels 17 km. How far is he from his starting point?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 5 km
Each turn is taken from the direction he is facing at that moment:
Facing East, a right turn is South (3 km)
Facing South, a right turn is West (3 km), as the question says
Facing West, a left turn is South (2 km)
Facing South, a right turn is West (17 km)
He goes \(20\) km East and then \(3+17=20\) km West, so the East-West moves cancel. He ends \(3+2=5\) km due South of the starting point.
