Many years ago, i did an experiment to discover this very fact.
I think i f**ked it up, and besides can't remember now.
I've read that it's approx 4 times faster than in air, is this true?
Well i suppose whilst we're at it, so then has anyone broken the "in water" sound barrier?

it is about 1500 meters/second or about 3000 miles/hour but it is effected by the temperature
it is true that it is about 4 times faster in water than air
no one has ever broken the speed of sound under water

Sound is a type of longitudinal, mechanical wave. They need a medium to propagate and will not travel through a vacuum. Sound travels at different speed in different media. The speed of sound is determined by the density (ρ) and compressibility (β) of the medium. Density is the amount of material in a given volume, and compressibility is a meaasure of how much a substance could be compacted for a given pressure. The denser and the more compressible, the faster the sound waves would travel. Therefore, the speed of sound is about four times faster in water than in air. The speed of sound in a medium can be determined by the equation …
v = (βρ)-1/2
Where …
v is the speed of sound,
β is the bulk modulus of elasticity, and
ρ (rho) is the density.
The speed of sound can also be affected by temperature. Sound waves tend to travel faster at higher temperatures. I have found different values for the speed of sound in water in different sources. They range from 1450 to 1498 meters per second in distilled water and 1531 m/s in sea water at room temperatures (20 to 25 °C).

Water is a medium and affects the speed of sound. You have to also know the temperature inorder for a correct answer.

The speed of sound in water is 1454M/sec
The speed in air is 332M/sec
When we are out sailing our boat, we can hear a motor boat before we can see it by the sound traveling through the water and coming in through the keel. When they are testing sonar in the area we can hear the sonar through the keel also.

speed=distance/time distance=speed*time The time represents a signal sent from the surface, to the bottom of the ocean, back to the surface. Therefore the time taken for the signal to travel to the underwater ship is only 1.03 s The distance is= 1369 m/s * 1.03 =1410 m
