One light year, which is 9,500,000,000,000km, or 9.5 trillion kilometers.
Radio wave travel faster than sound wave. Radio wave is the same as light wave except at different wavelength. It travel at speed of light (3 x 108 m/s). Sound wave travel at only 330 m/s and probably can go up to 3,300 m/s in solid medium which is far slower than the speed of light.
The question is too vague for an answer. It depends on the intensity of the radio wave source.
If there's nothing to stop it, any electromagnetic wave, such as radio or light, covers 25,902,068,370 kilometers (16,094,764,800 miles) in 24 hours.

Radio waves can travel indefinitely through space until they dissipate or are absorbed by particles in space. The farthest man-made radio signal, the Voyager 1 spacecraft, has been transmitting radio signals back to Earth from over 14 billion miles away.
