Question 200953
<font face="Garamond" size="+2">


The given 25 feet is a measure of height.  So just substitute 25 for *[tex \Large h] in your formula and do the arithmetic:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ t = \sqrt{\frac{h}{16}} = \sqrt{\frac{25}{16}} = \frac{\sqrt{25}}{\sqrt{16}}]


Take the two square roots and you have it.
