A person goes 6 km south, 8 km east, 4 km north, and 2 km west.
In which direction is he from the starting point?
Show answer & explanation
Correct answer: B
Explanation
Let the starting point be on a Cartesian plane where North is , South is , East is , and West is :
• Walks 6 km South: moves to
• Walks 8 km East: moves to
• Walks 4 km North: moves to
• Walks 2 km West: moves to
Net displacement from the origin is:
• Along East-West axis: (towards East)
• Along North-South axis: (towards South)
Therefore, the person is in the South-East direction from the starting point.
Correct Option: (B)
