The answer is right there in the words of the question.
Radio and light are the same physical phenomenon, and they travel at the same speed.
The star is 5 light years away. That means the distance that light ... and radio ... travel
in five years.
It takes light from the star 5 years to reach us, and it takes radio from us 5 years to reach
the star.

You can calculate the time it takes for a radio wave to reach a star using the speed of light, which is approximately 186,282 miles per second. Since the star is 5 light years away, you would multiply 5 by the number of seconds, minutes, or hours in a year (31,536,000 seconds, 525,600 minutes, or 8,760 hours) to find the time it takes for the radio wave to reach the star.

The moon is 382000000 m from earth how long does it take a radio signal to reach the moon and back to a reciver on earth show your work?
The time it takes for a radio signal to travel from Earth to the moon and back can be calculated using the formula: Time = Distance / Speed of Light. The speed of light is about 299,792 kilometers per second. So, Time = (382,000,000 * 2) / 299,792 = 508.8 seconds. Therefore, it takes approximately 508.8 seconds for a radio signal to reach the moon and return to Earth.
