A radio signal travels at 3 x 10^8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 x 10^7?

Answer 1

time = distance/speed, so

3.54x10^7 / 3x10^8 = 1.18x10^-1

or, 0.118 seconds
