Question

A man walks \(5\) km East, then turns right and walks \(4\) km, and then turns left and walks \(5\) km. In which direction is he finally moving?

• A. North
• B. South
• C. East
• D. West

Hint:

A quick trick: Right turn moves clockwise, while left turn moves anticlockwise on the compass directions.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question describes a sequence of straight-line movements and \(90^\circ\) turns.
We must track the facing direction of the person at each step to determine his final direction of travel.
Step 2: Detailed Solution:
Let's trace the journey step by step using standard map directions (North is Up, South is Down, East is Right, West is Left).
1. Initial movement:
The man starts walking \(5\) km towards the East. He is now facing East.
2. First turn:
He takes a right turn. If a person is facing East, a right turn is a \(90^\circ\) clockwise rotation.
He is now facing South. He walks \(4\) km in the South direction.
3. Second turn:
He then takes a left turn. If a person is facing South, a left turn is a \(90^\circ\) anti-clockwise rotation.
He is now facing East again. He walks \(5\) km in this direction.
4. Final orientation:
After the last movement, he is still walking in the East direction.
Step 3: Final Answer:
The man is finally moving towards the East.
