A radio travels at 3.00(10^8) meters per second. How many seconds will it take for the radio to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54(10^7) meters? Show your work.

Radio travels at a height of 300,000,000 meters.

Satellite orbits at a height of 35,400,000 meters.

35,400,000 / 300,000,000 ≈ 0.12

So it takes 0.12 seconds for the radio to reach the satellite that's orbiting earth.
