Concept:Track movement step-by-step using directions and distances relative to starting point.
Explanation:Let starting point be origin
(0,0).
Step 1: 10 m South →
(0,−10).
Step 2: Turn left (now East), walk 20 m →
(20,−10).
Step 3: Turn right (now South), walk 20 m →
(20,−30).
Step 4: Turn right (now West), walk 20 m →
(0,−30).
Step 5: Turn right (now North), walk 10 m →
(0,−20).
Final position is 20 m directly South of start.
