Show answer & explanation
Correct answer: A
Ravi starts at point A and walks 10 km North (to point B).
He turns right (East) and walks 20 km (to point C).
He turns right (South) and walks 10 km (to point D). He is now level with his starting point, but 20 km East.
He turns left (East) and walks 10 km (to point E). His total distance from the starting point is 20 km + 10 km = 30 km. His final direction from the start is East. Therefore, the correct answer is (a) 30 km East.
