1. The problem statement, all variables and given/known data In reference frame S two events occur at the same point; event A occurs 1.90 seconds before event B. In another frame, S′, event A occurs 2.45 seconds before event B. How far apart are events A and B in frame S′? 2. Relevant equations x'=gamma (x-vt) t' = [t - vx/c^2] gamma 3. The attempt at a solution I used the aforementioned mentioned Lorentz transformations. I know both T and t'. I'm trying to find x'. So I solved for x in both equations and tried to calculate x' but could not do so. Am I approaching the question correctly?
