Answers
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
