The speed of light is misleading. The speed of light is actually the speed of EM radiation.
All wavelengths of EM radiation travel at C and both radio waves and light travel at 300000km per second.
Microwaves, gamma rays, and x-rays are all the same thing, just with different amounts of energy, which differentiates them and their capabilities.
So to answer your question, both travel at C (speed of light = 3x10^8m per second), radio waves have a longer wavelength which means they have less energy).
You will see that visible light is just a small fraction of the EM spectrum. Our eyes are really limited in the informatio that they can pick up.

All electromagnetic waves including the radio waves travell at the same speed of light. A.A.Michelson, an American physicist, spent many years of his life in measuring the velocity of light & he devised a method in the year 1926 which is considered as accurate. The velocity of light determined by him is 2.99797*10 to the power8 m/s

Everything in the electromagnetic spectrum goes at the same speed. Light and radio waves are both in the electromagnetic spectrum, so they go at the same speed.

I would think that the speed of light travels at the fastest speed in the universe.

all electromagnetic radiation -- from radio waves to x-rays -- travel at the speed of light. In empty space this speed is approximately 300,000 kilometers per second!

From Infra Red, through visible to Ultra Violet, The Spectrum, Check it out, travel at the speed of `Light`. .........(Perhaps the speed of Spectrum would be more appropriate.)

At the same speed.

Radio waves are, as well as light, electomagnetic waves and they all have the same speed in vacuum = speed of light. :-)
