I'm hoping somebody who knows physics can help me out with this question...

If rocket A flys away from the earth at .866 the speed of light and rocket B flys away from the earth from the opposite side in the opposite direction at .866 the speed of light, then how can they still be moving < the speed of light away from each other?

I'm having trouble understanding how it works with these kind of paradoxes, twin paradox is something else I don't get.

Thanks if you can explain it in an intuitive way
