2. Turns West, moves 2 km.  

3. Turns South, moves 4 km → Now he's (7 - 4) = 3 km North from start.  

4. Turns West again, moves another 2 km → Total 4 km West.

So, from starting point, he's 3 km North and 4 km West.

Use Pythagoras theorem to find distance from start:

Distance = √(3² + 4²) = √(9 + 16) = √25 = 5 km
