B) 221 meters per second
C) 300 miles per hour

Answer:

D) 242 meters per second

Explanation:

The tsunami speed (or phase velocity) is independent of the wave period; it dispersion relation is given in terms of  the acceleration of gravity g by the following equation:

[tex]V=\sqrt{(g)(D)}[/tex]

Where D = water depth, and g = gravity (9.81 m /seg2)

Considering 6000meters as our water depth:

[tex]V=\sqrt{(9.81)(6000)}[/tex]

[tex]V=\sqrt{(58860)}\\V=242[/tex] meters per seconds

I hope you find this information useful and interesting! Good luck!
