My computer doesn't have a square root button
A tsunami travels at S=356(square root of d), s is speed in km/hr and d is the average depth in km. what is the depth of a tsunami travelling 130km/hr

s = 356 sqrt (d)
130 = 356 * sqrt ( d )
sqrt d = 130/356
d = (130/356)^2 = .365^2 = 0.133 km which is 133 meters which is about right
by the way
the speed of a shallow water wave (the whole ocean is shallow for a tsumani :) is about the square root (g h)
or about sqrt (10 m/s^2 * 133) = sqrt (1330) = 36.5 m/s * 3600 s/hr*1 km/1000 m = 131 km/hr
It checks :)
