Radio waves travel at the speed of light, approximately 300,000,000 m/s. Part A How much time does it take for a radio message t
jenyasd209 [6]

Answer:

Step-by-step explanation:

First you want to understand that every time a radio wave goes 300,000,000 meters a second passes, literally what meter per second means.    of course it doesn't go that far, it goes 384,000 one way and then the same distance back, which makes 768,000.  Under a third of the distance to make 1 second, so it will be less than one second.  

You also want to understand the formula for speed.  speed = distance / time.  Whch also means, to find time you can change it to be time = distance / speed.  And hey, we have distance and speed.  768,000 / 300,000,000 = .00256, I'll leave the significant figures to you unless you need help with them.  but that's .00256 of a second.  or .00256 s
