System S’ has a velocity u = +0.56c relative to system S, as shown in the figure. The clocks of S and S′ are synchronized at t = t′ = 0 when the origins O and O′ coincide. An event is observed in both systems. The event takes place at x =1200 m and at time t = 3.0 μs as measured by an observer in S. What is the time t′ of the event, measured by an observer in S′?
