Vansh travels 3 km in the East and turns to South and moves 4 km. How far is he from the starting point?

give me a answer plz​

Answer 1

Given :- Vansh travels 3 km in the East and turns to South and moves 4km. How far is he from the starting point .

Answer :-

Let starting point is A .

so, from A he travel 3 km east . Let he reached at B .

then,

→ A -------------- B

→ AB = 3 km .

now , from B he travel 4 km in south . Let he reached at point C .

then,

→ A ------------- B

C

→ BC = 4 km.

therefore,

→ A = Starting point

→ C = End point .

using pythagoras theorem we get,

→ AC = √(AB² + BC)²

→ AC = √(3² + 4²)

→ AC = √(9 + 16)

→ AC = √25

→ AC = 5 km (Ans.)

Answer 2

Given:

Vansh travels 3 km in the East and turns to the South and moves 4km.

To Find:

How far is he from the starting point?

Solution:

Refer to an attachment to understand clearly how Vansh travels and what we need to find.

• We need to find the distance traveled between the starting point(A) and ending point(C)

• See attachment AB = 3km and BC = 4 km. we need to find the distance of AC.

We can find this easily by using Pythagoras Theorem.

$= > {AC}^{2} = {AB}^{2} + {BC}^{2}$

$= > {AC}^{2} = {3}^{2} + {4}^{2}$

$= > {AC}^{2} = 9 + 16$

$= > AC = \sqrt{25}$

$= > AC = 5$

Hence, The distance between the starting point and ending point is 5km.
