The maximum walking speed $\displaystyle S$ (in feet per second) of an walking animal is given by the function $\displaystyle S = \sqrt{GT}$ where $\displaystyle G$ is $\displaystyle 32$ *feet per second squared* and $\displaystyle L$ is the length of the animal's leg (in feet)

How fast can an animal whose legs are $\displaystyle 9$ inches long walk?

Round off your answer to the nearest hundredth.

The answer to this is $\displaystyle 12\sqrt{2}$ or $\displaystyle 16.97 $but don't see how this was derived
