Keilah, in reference frame S, measures two events to be simultaneous. Event A occurs at the point (53.0 m, 0, 0) at the instant 9:00:00 Universal time on January 15, 2010. Event B occurs at the point (180 m, 0, 0) at the same moment. Torrey, moving past with a velocity of 0.760c, also observes the two events. In her reference frame S', which event occurred first? What time interval elapsed between the events?
