Answer:
1430 m/s
Step-by-step explanation:
In this problem, the speed of sound in water is given by:
![v=(d)/(t)](https://img.qammunity.org/2020/formulas/physics/high-school/jidcwnxn1c0zdocnxtzp97sqgn187ivyra.png)
where
d is the distance travelled by the sound in water
t is the time taken
In this problem, we have:
d = 6,006 m
t = 4.2 s
So, the speed of sound in water is
![v=(6,006 m)/(4.2 s)=1430 m/s](https://img.qammunity.org/2020/formulas/physics/high-school/lonejlir1edx3kidzbo52vvoftu3ww40oa.png)
