In inertial frame S, a red light and a blue light are separated by a distance ?x = 2.45 km, with the red light at the larger value of x. The blue light flashes, and 5.35 ?s later the red light flashes. Frame S' is moving in the direction of increasing x with a speed of v = 0.855 c. What is the distance between the two flashes and the time between them as measured in S'?
