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