Radio signals travel at a rate of 3x10%5E8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of the Earth if the satellite is orbiting at a height of 3.6x10%5E7 meters?
----------------
d = rt
t = d/r = 3.6E7/3E8
t = 1.2E-1 = 0.12 seconds.
