`[G] [A---1 light-second-----B]`

------> 0.8c

George (designated by the G) is watching his friends Sue (location A) and Sally (location B) zoom away from him at 0.8c. His friends are located at both ends of a spaceship 1 light-second long. From George's point of view, the ship is only 0.6 light-seconds long. Sue sends a light beam to Sally and it only takes 1 second to get from Sue to Sally. According to George, because Sally is running away from the light, the trip actually takes 0.6/0.2 = 3 seconds. So 1 second for Sue and Sally is equal to 3 seconds for George. Sally decides to send a beam of light to her friend Sue. Once again, it takes 1 second to get from Sally to Sue. Because Sue is racing towards the beam of light, according to George the trip takes 0.6/1.8 = 1/3 seconds. So 1 second for Sue and Sally is equal to 1/3 seconds for George.

So which is it?

Is 1 second for Sue and Sally equal to 3 seconds for George or 1/3 seconds for George?
