5km
Reasoning: Person walked 10km straight and turn to his right side(90’ clockwise) he continued to walk for another 4km and turned again to his right side. From here he is travelling back towards the starting point but at 4km away in parallel so traveled 7km and 3kms are left now here we apply the equation
a^2+b^2 = c^2
a = 3
b =4
So,
9+16 = c^2
c^2 = 25
Take square root on both sides
C = 5
