Priya walks 15 m south, then turns to her left and walks 20 m. She then turns right and walks 9 m. How far is she from her starting point?
This item is invalid as written because the computed distance is not among the options.
- A25 m
- B24 m
- C20 m
- D26 mCorrect
Explanation
South 15 m, left from south faces east, so 20 m east, then right from east faces south, so 9 m south. Net: 24 m south and 20 m east. Distance = √(24² + 20²) = √(576 + 400) = √976, not a perfect square, so recheck: using 15 + 9 = 24 south and 20 east gives √976 ≈ 31.2 m.
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.
