The speed that a tsunami can travel is modeled by the equation [tex]S=356 \sqrt{d}[/tex], where [tex]S[/tex] is the speed in kilometers per hour and [tex]d[/tex] is the average depth of the water in kilometers.
What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour?
A. [tex]0.32 \, \text{km}[/tex]
B. [tex]0.75 \, \text{km}[/tex]
C. [tex]1.12 \, \text{km}[/tex]
D. [tex]3.17 \, \text{km}[/tex]
