c_(water) = 2.25* 10^(8)m/s

Step-by-step explanation:

The speed of light in any medium is given by

$c = \lambda \\u$

where
$\lambda$ is the wavelength and
$\\u$ is the frequency. In water,

$c_(water) = \lambda_(water) \\u$

$\:\:\:\:\:\:\:\:= (3.75* 10^(-7)\:m)(6* 10^(14))\:Hz$

$\:\:\:\:\:\:\:\:= 2.25* 10^(8)\:m/s$
