# How Far is He From The Starting Point? If

Kailash walks 3 km to East and turns South and walks 4 km. Again turns West and Walks 6 km. How far is he from the starting point?

- 5 km
- 6 km
- 7 km
- 3 km

**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 = (altitude ^{2} + base^{2})^{1/2}**

Then, the hypotenuse = (4

^{2}+ 3

^{2})

^{1/2 }= (16 + 9)

^{1/2}

= (25)

^{1/2}

=5 km

Hence, the distance from the starting point = 5 km
