Answer 1

Answer:

Option 1) 5 km

The distance from the starting point to Vansh's final position is 5 km.

Step-by-step explanation:

Vansh travelled = 3 km towards east

Then he travels = 4 km towards south

Distance from starting point.

Starting point is A and final point is C. So, the distance from the starting point to the final point is x.

We can solve it by Pythagoras theorem,

• Hypotenuse = x = AC
• Base = 3km = AB
• Height = 4km = BC

★ (Hypothenuse)² = (Base)² + (Height)²

⇒ (x)² = (3)² + (4)²

⇒ x² = 9 + 16

⇒ x² = 25

⇒ x = √25

⇒ x = 5

Hypothenuse = 5 km

Therefore, the distance from the starting point to Vansh's final position is 5 km.

Answer 2

Given :-

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

To Find :-

Far from starting point

Solution :-

We know that

Hypotenuse² = Base² + Height²

H² = 3² + 4²

H² = 9 + 16

H² = 25

√H² = √25

H = 5

Hence,

Vansh is 5 km far from the starting point

Option A is correct.
