Technically, the speed of sound in air is known as Mach numbers, Mach 1, Mach 3 and so on. These do not correspond with kph (or mph), for the Mach number is related to the speed of sound in that atmosphere.
The speed of sound drops as the altitude increases, for the molecules are farther apart. So a plane will have to travel less km/h at 20 000m (295m/s) than at sea level (340 m/s) for Mach 1.
If you look up speed of sound in wikipedia, you'll find a nice pic of a plane breaking the sound barrier.

How does the speed of sound in steel compare with the speed of sound in air?
The speed of sound in steel is much faster than in air. In general, sound travels at about 5,960 m/s in steel, while it travels at about 343 m/s in air at room temperature. The higher density and stiffness of steel allow sound waves to propagate more quickly through it compared to the lighter and less dense air.
The speed of sound in what is greater than the speed of sound in water?
Speed of sound in water is faster than in air. Speed of sound in steel is c = 5930 m/s. That is faster than in air and in water. Speed of sound in water is c = 1480 m/s. It is affected by the oceanographic variables of temperature, salinity, and pressure. Speed of sound in air is c = 343 m/s at 20°C = 68°F. The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).
What is the speed of sound in medium air?
The speed of sound in air at 25 degree Celsius is 343m/s.
What is the speed of sound in air when the temperature is 20CC?
At a temperature of 20°C, the speed of sound in air is approximately 343 meters per second. The speed of sound in air increases with temperature, as sound travels faster in warmer air due to higher molecular vibrations.
What is the speed of sound at 12 degree Celsius?
Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 12 °C is c ≈ 331 + 0.6 × 12 = 338.2 m/s.
Which is faster the speed of sound or the speed of air?
The speed of sound depends on the air factors around it
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
Which is faster the speed of sound in air or the speed of light in air?
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
How does the speed of sound in air compare to the speed of sound in solid?
The speed of sound in air is approximately 343 meters per second, while the speed of sound in solids can vary but is generally higher than in air. In solids, sound waves travel faster due to the denser medium and stronger intermolecular bonds.
Why is the speed of sound in nitrogen similar to the speed of sound in air?
This is because air is 78% nitrogen.
The speed of sound in a solid is what than the speed of sound in air?
greater
Why is the speed of sound in air faster than the speed of sound in solid?
its not
Is the speed of sound in the air different or the same as the speed of sound in the water?
No, it is not.
What happens to speed of sound in air when sound get louder?
The loudness of the sound has no effect on its speed.
What is the speed of sound in dry air at 20C?
The speed of sound at 70oC is 371.333m/s. Refer to the related link below for a calculator for the speed of sound in air.
What is the speed of sound in air at 42.0 ºC?
Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 42°C is c ≈ 331 + 0.6 × 42 = 356.2 m/s.
How do the speed of light and the speed of sound compare through air?
The speed of light is significantly faster than the speed of sound in air. The speed of light in a vacuum is approximately 299,792 kilometers per second while the speed of sound in air is about 343 meters per second. This means that light travels almost a million times faster than sound through air.
