Answer:

5000 ft.

Step-by-step explanation:

Refer the attached figure .

AC is the distance of hulk from home

Since ΔABC is right angled triangle. we will use pythagorus theorem.

$Hypotenuse^{2} =Perpendicular^{2} +Base^{2}$

Hypotenuse = AC

Perpendicular = AB=6 blocks

Base = BC = 8 blocks

⇒ $AC^{2} =AB^{2} +BC^{2}$

⇒ $AC^{2} =6^{2} +8^{2}$

⇒ $AC^{2} =36+64$

⇒ $AC^{2} =100$

⇒ $AC =\sqrt{100}$

⇒ $AC =10$

Thus AC = 10 blocks .

Since we are given each block is 500 ft.

Thus 10 blocks = 500*10=5000ft.

Hence hulk is 5000 ft away from the home
