Question

A person travels 12 km due North, then 15 km due East, after that 15 km due West and then 18 km due South. How far is he from the starting point?

• A. 6 km
• B. 12 km
• C. 33 km
• D. 60 km

Hint:

For these types of questions, break the movement into components (North-South, East-West) and calculate the net displacement in each direction.

Answer 1

The Correct Option is A

The person first moves North, then East, then West, and finally South: - After moving 12 km North, the person moves 15 km East, then 15 km West (returning to the original East-West position).
- Finally, moving 18 km South, the net displacement is 18 km South - 12 km North = 6 km South.
Thus, the person is 6 km from the starting point.
