A man walks 25 m north, then 20 m east, then 10 m south. In which direction is he from his starting point?
Answer and explanation
Correct answer: C. north-east
- Step 1: Find the net position vector relative to origin : movement north is , movement east is , movement south is .
- Step 2: Compute the coordinates: (positive indicates North), and (positive indicates East).
- Step 3: Combining the positive axis directions gives the relative quadrant direction: North-East.
Answer
north-east.
Why not the others: south-east has a negative vertical coordinate (south); north-west has a negative horizontal coordinate (west); south-west has both coordinates negative.
