The speed of sound depends on the medium through which it is being transmitted.
In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three seconds or approximately one mile in five seconds.
In fresh water, sound travels at about 1482.3 m/s at 20 °C.
As a ratio, sound travels 4.3 times as fast in water as it does in air at 20 °C (or 3.3 times faster if you want to play with semantics). The ratio at other temperatures is similar.

How many times faster is the speed of light in a vacuum than the speed of sound air?
100% - sound is vibration of atoms/molecules - it cannot travel through vacuum ___________________________ The idea of "speed pf sound in a vacuum" is meaningless; sound cannot travel without a medium such as air, water, metal, stone, or SOMETHING. Sound waves are mechanical vibrations; there has to be something to vibrate. The speed of sound in air is around 700 miles per hour, while the speed of light is 186,000 miles per SECOND.
When the body is in water how many times faster does it lose heat than when it is in still air?
The body loses heat around 25 times faster in water than in still air due to water's high thermal conductivity. This rapid heat loss can lead to hypothermia in cold water even if the air temperature is warm.
In what material does sound travel through the fastest?
There are too many 'materials' to list but generally, sound travels faster in solids than in liquids, and faster in liquids than in gases. In other words, the denser the material, the faster sound travels.
Why does sound travel slower through liquids?
It doesn't, sound travels slowest in air then faster in liquids then solids. Sound traveling through steel in many times faster then through air, for example. Sound travels through vibrations, and the vibrations pass through molecules until they reach your ear. If the molecules are far away it takes longer to pass the vibrations, but if they are closer together they will travel faster. Because the molecules are packed closer together in a liquid the sound travels faster through it, and even faster through solids.
Does sound travel faster through glass windows or walls?
AnswerSound will travel faster through glass than most wall materials. But a better question might be which material is more sound proof. The answer to that would be walls (without windows). Generally if a material or structure can leak air, it can leak sound proportionally.The actual speed that a material transmits sound is proportional to its density. Water, being far more dense than air transmits sound much faster... so much so that it is difficult to determine the direction of an underwater sound without the time lag between ears, to which we've become accustomed. Sound travels through steel many times faster than that.Likewise, sound travels slower at higher altitudes due to the decreased density of the atmosphere. This is why sometimes the speed of sound will be referred to in aviation circles by noting, 'at sea level' -- an important point, since the sound barrier at altitude may be far slower.
How many times faster does sound travel through steel than through air?
15 times faster
How many times sound travel faster in solid as compared to liquid?
It depends on the temperature, the elasticity, and the density.
How many times faster than the speed of sound can you travel?
No real limit, up to the speed of light. The Apollo astronauts traveled at ABOUT 32 times the speed of sound on their trip to the moon. That is the fastest yet.
How many times faster is the speed of light in a vacuum than the speed of sound air?

Why do you hear lighting long after you see the flash?
You hear the sound, called thunder, after the flash because light travels many times faster than sound and therefore reaches you first.
What is an aircraft that flies faster than the speed of sound called?
The type of aircraft that flies faster than the speed of the sound are called SuperSonic aircraft.There are many supersonic aircrafts. Nowadays there are also HyperSonicaircrafts. The maximum speed recorded is Mach 9.6 (9.6 times faster than the speed of sound) by X-43A.
What material does sound travel through the fastest?
There are too many 'materials' to list but generally, sound travels faster in solids than in liquids, and faster in liquids than in gases. In other words, the denser the material, the faster sound travels.

How many miles per hour can supersonic fly?
Mach refers to the speed of sound in air. Typically about 750 mi/hr but it varies faster or slower with temperature from cold to hot respectively. Mach one is one times speed of sound. Mach 3 would be three times speed of sound.
How many times faster is a FireWire 800 port than a FireWire 400 port?
two times faster
How many times is a peregrine falcon faster then a cheetah?
About 3 times
How many times greater is the speed of light than the speed of sound?
The speed of sound in air is about 300 meters per second. (320 is closer still). ..The speed of light in a vacuum is 300 000 000 meters per second.So the speed of light in a vacuum (in air it is only slightly different) is about one million times the speed of sound in air.
