Neha walks 10 m east from her house to reach a park. From the park she walks 4 m south, then 6 m west, and then 4 m north to reach a library. In which direction is the library from her house, and how far is it?
The library is 4 m east of her house. Her east-west movement is 10 m east minus 6 m west, giving 4 m east, while the 4 m south and 4 m north legs cancel. So the displacement is purely eastward and equals 4 m.
- A4 m, eastCorrect
- B6 m, east
- C10 m, west
- D16 m, east
Explanation
Net east-west movement: +10 - 6 = 4 m east. Net north-south: 4 south and 4 north cancel to 0. So the library is 4 m east of the house. The 6 m option ignores the 10 m east leg correctly only as a partial value and is wrong.
