Neha walks 15 m south, then turns to her left and walks 20 m, and then turns to her left again and walks 15 m. How far is she from her starting point?
Neha is 20 m from her starting point. After going 15 m south, left turns take her 20 m east and then 15 m north, which cancels the southward movement, leaving her exactly 20 m east of the start.
- A20 mCorrect
- B35 m
- C25 m
- D15 m
Explanation
Facing south, her left is east, so she walks 20 m east. Turning left again she faces north and walks 15 m, cancelling the earlier 15 m south. She is 20 m east of the start. Using Pythagoras with 0 m vertical gives 20 m; 25 m would wrongly ignore the 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.
