Question
A man walks 10 m north, turns right and walks 15 m, then turns right and walks 10 m. How far is he from his starting point, and in which direction?
Options

- 15 m west
- 25 m east
Show the answer and the worked solution
Correct answer: B. 15 m east
Worked solution
- North 10 m, then right (east) 15 m, then right (south) 10 m.
- The northward and southward 10 m cancel, leaving 15 m east of the start.
Answer: 15 m east.
The idea
Track the north–south and east–west totals separately, adding for one direction and subtracting for its opposite. Sketch even when the numbers look easy.
Shortcut. Two right turns reverse the heading, so the third leg undoes the first; only the 15 m middle leg, heading east, remains.
Common trap. "15 m west" — taking a right turn from north as west; facing north, right is east.
