We can use the formula:
time = distance / speed
where distance is the height of the satellite above the Earth's surface, and speed is the speed of the radio signal.
Plugging in the 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 the radio signal to travel from the satellite to the surface of Earth.
