it is about 300,000 kilometers per second.
Same as the speed of light.
3x10^8 m/s or 186,200 miles per hour
The same as speed of light in vacuum, which is one case of electromagnetic radiation, i.e. 299792458 m/s.
Microwaves are electromagnetic waves, meaning that in a vacuum, they move at the speed of light. In air, they move slightly slower, but for most practical purposes, it doesn't make much difference.
Normally a vacuum does not move of its own accord.

Zero. Sound cannot travel in a vacuum.
A vacuum doesn't travel. All electromagnetic wavestravel at the same speed in vacuum.
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.

Yes. The light is an example of a electromagnetic wave and its speed is constant.
The speed of every electromagnetic wave is 299,792,458 meters per second in vacuum, regardless of its frequency.

In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.

No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.
The speed of every electromagnetic wave is 299,792,458 meters per second in vacuum, regardless of its frequency.
All electromagnetic waves travel at the same speed in vacuum.
Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
