A telephone pole is 55 feet tall. Jeri stands in the shadow of the pole. She is 66 inches tall, gut her shadow is 12 feet long. How far away from the telephone pole is she standing?
I will assume her shadow coincides with the end of the pole's shadow
let her distance from the pole be x ft
66 inches = 5.5 ft
so by ratios:
55/(x+12) = 5.5/12
5.5x + 66 = 660
5.5x = 594
x = 108
She is standing 108 ft from the pole.
