Meera walks 12 m towards the north, then turns right and walks 9 m. She then turns right again and walks 12 m. How far is she from her starting point and in which direction from it?

Meera ends 9 m east of her starting point. Her 12 m north and 12 m south walks cancel each other, and only the 9 m eastward movement remains, so both distance and direction come from that single leg.

  1. A9 m, eastCorrect
  2. B9 m, west
  3. C12 m, east
  4. D21 m, south-east

Explanation

Take the start as (0,0). North 12 m gives (0,12). Turning right means east, so 9 m gives (9,12). Turning right again means south, so 12 m gives (9,0). She is 9 m east of the start. Option 9 m west would come from turning left at the first turn.

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.
