Ishita walks 16 m south from her gate, then 12 m east, then 8 m north, and then turns west and walks 12 m to stop at point Q. How far is Q from the gate and in which direction?
Q is 8 m south of the gate. The southward 16 m is partly offset by the 8 m northward walk, leaving 8 m south, while the 12 m east and 12 m west legs cancel completely, so there is no sideways displacement.
- A8 m southCorrect
- B8 m north
- C20 m south-east
- D12 m south
Explanation
Net north-south: 16 m south minus 8 m north gives 8 m south. Net east-west: 12 m east minus 12 m west gives 0. So Q is 8 m directly south of the gate. Saying 12 m south would ignore the 8 m northward leg, and 8 m north would reverse the net direction.
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.
