If you're looking out you're window which is 32 feet from the ground, and you're neighbors yard is 20 feet away, in which there is a 8ft fence, how many feet past the fence will you first see the ground?

Solution

Using proportions:

$$\frac{x}{8} = \frac{x + 20}{32}$$ $$32x = 8(x + 20)$$ $$32x = 8x + 160$$ $$24x = 160$$ $$x = \frac{160}{24} = \frac{20}{3}ft \approx 6.7ft.$$

Answer: $\frac{20}{3}ft \approx 6.7ft$.
