The speed, v, of a wave is inversely proportional to the square root of the

yKpoI14uk [10]

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

$v \sqrt{d}$ = k

If v = 30 and d = 400, then

30( $\sqrt{400}$ ) = k

k = 30(20) = 600

Now $v \sqrt{d}$ = 600

If d = 25, then v $\sqrt{25}$ = 600

5v = 600

v = 120
