0.3432 km.sec-1 in dry air at 20oC. For information about the speed in other media, and other factors affecting speed, you may wish to consult the wikipedia page about the speed of sound.
Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.

I guess you refer to the speed of sound. The speed of sound depends on the material sounds goes through, as well as temperature, pressure, humidity, among others. For example, the speed of sound in air is around 350 meters/second; in some other materials it can be several times as fast.
The speed of sound is measured by timing how long it takes for a sound wave to travel a known distance. By dividing the distance by the time taken, the speed of sound can be calculated.
The speed of sound in space is zero because there is no medium for sound waves to travel through. In other mediums, such as air or water, the speed of sound varies depending on factors like temperature and density.
50 kilometres per hour is your average speed.
The Lockheed-Martin SR-71 Blackbird's top speed was Mach 3.5, or 3.5 times the speed of sound. that is 2664 miles per hour and 4287 kilometres per hour

No, the speed of sound is faster in solids.
The speed of light is much greater than the speed of sound.
The M1 and its variants have a top road speed of 67.7 kilometres per hour (42 mph), and an offroad top speed of 48.3 kilometres per hour (30 mph).
The units cannot be converted. Kilometres are a linear measurement, kilometres per hour indicate a speed.
The Sound of Speed was created in 1988.
The loudness of the sound has no effect on its speed.
the top speed is 205 miles per hour, or 330 kilometres an hour.
The speed of light is about 900,000 times as fast as the speed of sound in air.
