Radio signals travel at a rate of 3 * 10^8 meters per second. How many seconds would 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 9.6 * 10^6 meters? (1 point)

3.2 x 10^2 seconds
3.2 x 10^-2 seconds
3.13 x 10^1 seconds
2.88 x 10^15 seconds

I think I'm close to getting it... but I'm still not quite sure. Please help?
