Question

The speed of a tsunami , in metre per second can be found by the formula r = √9.7344d , where d is the water depth. If water depth is 6400m. How fast is the tsunami moving ?​

Answer 1

Answer:

r = √(9.7344d )

 = √(9.7344* 6400 )

 = 249 . 6 ( answer )

Answer 2

The correct answer is 249.6 m/sec.

Given: The equation = $r=\sqrt{9.7344d}$.

To Find: Speed of tsunami when d is 6400m.

Solution:

$r=\sqrt{9.7344d}$

Put the value of d in the equation.

$r=\sqrt{9.7344*6400}$

$r=3.12*80$

r = 249.6 m/sec

Hence, the speed of tsunami is 249.6 m/sec.
