Given that a satellite signal travels at the speed of light exactly how long does it take for a signal to go from the Earth to a satellite in geosynchronous orbit and back to Earth Show the calculat?

The speed of light is equal to approximately 186,000 miles per second. Geosynchronous-Earth-orbit satellites are found 22,300 miles from Earth and are always positioned over the same point on Earth.

The signal has to go to the satellite which is 22,300 miles up, and then back to Earth which is 22,300 miles back. So the total distance traveled is 44,600 miles.

To get the amount of time it takes simply do 44,600/186,000 = approximately .23978 seconds. Or you could say 239.78 milliseconds.

Hope this helps.
