A radio signal travels at 3.00x10^8 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 3.54x10^7? Show your work

1 answer

The distance the radio signal needs to travel is the distance from the satellite to the surface of the Earth, which is 3.54x10^7 meters.

Using the formula distance = rate x time, we can solve for the time:

distance = rate x time
3.54x10^7 meters = 3.00x10^8 meters/second x time

Dividing both sides by 3.00x10^8 meters/second, we get:

time = 3.54x10^7 meters / 3.00x10^8 meters/second
time = 0.118 seconds

Therefore, it will take 0.118 seconds for the radio signal to travel from the satellite to the surface of Earth.
