A tsunami (commonly called a " tsunami " because of its effect is a rapid change in the tide ) is a fast-moving ocean wave caused by an undersea earthquake . The water first passes below its normal level , then rises at the same distance around its normal level , and finally returns to normal , the period is approximately 15 minutes.


Suppose that a tsunami with an amplitude of 10 meters closer spring Honolulu, where the average depth of water is 9 meters.

I do not see a problem , so if a = b , then a ^ 2 = ab a ^ 2 - b ^ 2 = ab - b ^ 2 (a, b ) x (a - b) = b x (a - b )
(ab ) x (a - b) / ( a - b ) = bx (a - b) / ( a - b )
a, b = b a = bb as substitute for , then
b b = b 2 x b = b 2 x b / b = b / b 2 = 1

The water would go down the same amount that it goes up so we would start with 10m. OOOHhhh! but there is only 9m of water there so it can only go down 9m. this means it can only go up 9 meters. 9 + 9 is a maximum depth of 18m.

Gary, that's a good one, but one mistake...
you said that a=b, thus you cannot divide by (a-b) b/c that equals zero, and you cant divide by zero.
