Ritu walks 6 m east, then 8 m north, then 6 m west. How far is she from her starting point?
She is 8 m from her starting point. The eastward and westward walks of 6 m cancel each other, so only the 8 m northward displacement remains, and no Pythagoras calculation is needed.
- A8 mCorrect
- B10 m
- C6 m
- D20 m
Explanation
The 6 m east and 6 m west cancel, leaving only 8 m north. Distance = 8 m. Option 10 m wrongly treats the first two legs as a right triangle and ignores the westward walk.
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.
