Keilah, in reference frame $\mathrm{S},$ measures two events to be simultaneous. Event A occurs at the point $(50.0 \mathrm{m}, 0,0)$ at the instant 9: 00: 00 Universal time on January 15,2010. Event $\mathrm{B}$ occurs at the point $(150 \mathrm{m}, 0,0)$ at the same moment. Torrey, moving past with a velocity of $0.800 c \hat{\mathbf{i}},$ also observes the two events. In her reference frame $S^{\prime},$ which event occurred first and what time interval elapsed between the events?
