Answer:

look, 1st :take a point

2nd :as it mentions 8 kms west it should go left {mark as 8 kms}

3 rd:while walking west right will be towards north {upwards}so petr walks 3 kms north which does nt change how far is he from it

4th: now the right will be east {right side }and will increase distance

     this is 12 kms but it will cover the 8 kms so we subtract and get 4

            12km

 .-----------------------↔-------.↑-------------------*{end point}

 .                                        ↑.              *

 .                                        ↑.      *

 ^3kms{up}.---------↔------.(starting point<)

here a triangle is formed so we do pythogras theroram to find the distance

3^2  +  4^2   = x^2

9+16= x^2

25 = x^2

{square root}√25=x

5 = x

hope i helped , if i did mark me as brainliest
