$2.(10$ pts$)$ Calculates the speed of a tsunami in meters per second according to the

formula

where and $=2100$ is the depth of the ocean in meters and assigns the

result to the variable velTsunami.

$3.(20$ points$)$ Create an external function $$MpsToKmph$.$m$$ for m$/$s to km$/$h conversion, that takes an input argument in m$/$s and outputs a value in km$/$h$.$

$4.($a$)(10$ pts$)$ Calculate the wave speed of the tsunami in km$/$h using your external

function $$MpsToKmph$.$m$,$ and print the speed in km$/$h using the disp function.

$($b$)(10$ pts$)$ Calculate how far, in km$,$ the wave will travel in $8$ hours, $12$ hours, $24$ hours.
