Answer:

The height of the telephone pole is of 408 inches = 34 ft.

Step-by-step explanation:

Each foot has 12 inches.

A 36 inch post cast a shadow of 24 inches.

This means that the shadow is [tex]\frac{24}{36} = \frac{2}{3}[/tex] of the real height.

At the same time a telephone pole cast a shadow of 22 ft 8 in.

Each feet has 12 inches, so it has:

22*12 + 8 = 272 in.

2/3 of the real height is 272 in. So

[tex]\frac{2h}{3} = 272[/tex]

[tex]h = \frac{272*3}{2}[/tex]

[tex]h = 408[/tex]

The height of the telephone pole is of 408 inches = 34 ft.
