Concept:Track the net displacement from the starting point to find the final direction.Explanation:Let the starting point be (0,0).North is positive y, East is positive x.Step 1: Walk 15 m South → (0,−15).Step 2: Walk 20 m North → (0,−15+20)=(0,5).Step 3: Walk 10 m East → (10,5).Step 4: Walk 5 m South → (10,5−5)=(10,0).Final position: (10,0), which is 10 m East of the start.Answer:East
