    A basketball player is 6 feet 8 inches tall. How far should he stand from the light which is 15 feet above the ground, in order to cast a shadow 25 feet long?
    Solution: Ratio and Proportion

    6 feet 8 inches = 6 + \( \frac{8}{12}\) = \(\frac{20}{3}\) feet

    \( \frac{15}{x+25}\) = \( \frac{\frac{20}{3}}{25}\)

    \(15(75) = 20 (x+25)\)

    \( 1125 = 20x +500 \)

    \(x = \frac{1125-500}{20}\)

    \(x = 31.25\)
