at a rough guess, i,d say 2 minutes as it,s our nearest neighbour

Anywhere between 2minutes 18seconds and 14minutes 20seconds, depending on where the two planets are in their respective orbits.
It would be a tie; both light and radio are electromagnetic waves, as are X-rays, gamma rays, ultra-violet and infrared. They all travel at the same speed, the "speed of light", which is about 300,000 km/second, or 186,000 miles per second.
At the moment - according to the Wikipedia article (see related link) it takes about 16 hours for signals sent from Voyager to reach Earth. At least that's what it says in the section titled 'Current Status'
Keep in mind that radio waves are measured, and travel by the wavelength and frequency. If you know any information about the signal (strength, wavelength, frequency, etc), these can often be translated to total energy and speed of travel. This calculation can be general, or made very precise (often involving an interesting constant, the "permittivity of free space"). Remember that frequency is often measured in inverse distance units, so 1/cm or cm^-1. These can be easily converted to standard units (meters) and translate to energy and speed. Using the distance from Venus to Earth, the total time to travel can be determined.

Depending on their positions in their respective orbits, it could be Venus or Mars. The fastest would be when Venus is at inferior conjunction. That is when Venus and Earth are in line with and on the same side of the Sun. In this case the distance would be approximately 40 000 000 km and a radio signal would take approximately 2 minutes to reach Venus.
0.301 seconds
It's not clear what the number in the question refers to. The frequency or wavelength of the signal have no effect on the time required for it to reach earth. The only important number is: How far it has to travel. The signal would take 1 hour for every 670,615,200 miles it has to cover.
It depends on how fast you are travelling.

*Homework question* The speed of light (c) is about 300,000 kps. So (382,000,000 / (c*1000)) * 2 = <Answer>

Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
