Answer: (1) 5 km

Explanation:-
Kailash walks in East direction = 3 km
He turns in South direction and he walks = 4 km
Again he turns in West direction and he walks = 6 km

In the distance makes a right triangle which altitude = 4 km  & base = 3 km
Hypotenuses = ?

Formula –
Hypotenuse = (altitude2 + base2)1/2
Then, the hypotenuse = (42 + 32)1/2
 = (16 + 9)1/2
= (25)1/2
=5 km

Hence, the distance from the starting point = 5 km
