1. use the formula s(d)=√9.8d to calculate the estimated speed, in meters per second, of a tsunami if the disturbance occurred at an ocean depth of 4,500 meters.

2. convert the answer from question one from meters per second to kilometers per hour. (hint: a meter per second is equal to 3.6 kilometers per hour.)

1. 210 meters per second .

2.  756  kilometers per hour.

Step-by-step explanation:

Given : The formula to calculate the estimated speed, in meters per second of a tsunami.

1. If the disturbance occurred at an ocean depth of 4,500 meters.

Then put d= 4500 in the above formula , we get

Hence, if the disturbance occurred at an ocean depth of 4,500 meters , the estimated speed would be 210 meters per second .

Also, A meter per second is equal to 3.6 kilometers per hour.

i.e. 1 meter per second = 3.6 kilometers per hour

Then by unitary method ,

210 meters per second  = kilometers per hour

=756  kilometers per hour.
