Answer 1

Answer:

15$\sqrt{2}$

Explanation:

His displacement from the source after walking 20 m South and 15 m West is 25 m South West (from vector addition).

Since he walks 5 minutes North, his displacement from the starting point would be $\sqrt{(15^2)+(15^2)}$

You can easily find the answer if you properly draw the position vectors.
