Sunil walks 15 m west, turns north and walks 20 m, then turns east and walks 15 m. How far and in which direction is he from his starting point?

Sunil is 20 m north of his starting point. The 15 m west and 15 m east legs cancel each other exactly, so only the 20 m northward leg contributes to his displacement. The final position lies directly north of the start.

  1. A20 m northCorrect
  2. B30 m north
  3. C35 m north
  4. D20 m south

Explanation

The 15 m west and 15 m east cancel, leaving only the 20 m north movement. So he is 20 m due north of the start. The 35 m option adds the 15 m wrongly, and 30 m ignores the net cancellation.

Did you get it right without looking?

One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
