We can use the formula:
time = distance/speed
The distance is the height of the satellite above Earth's surface, which is 3.54 x 10^7 meters.
The speed is the speed of the radio signal, which is 3.00 x 10^8 meters per second.
Plugging in these values, we get:
time = 3.54 x 10^7 meters / 3.00 x 10^8 meters per second
time = 0.118 seconds
Therefore, it will take 0.118 seconds for a radio signal to travel from a satellite to the surface of Earth.
