expression of 𝑥 from sub-section ‘B’ above, one gets 𝑡 = √[𝑡′2 + (−𝑥′2 + 𝑥′2(1−𝛽2)) / 𝑐2] = √[𝑡′2 − 𝛽2𝑥′2 / 𝑐2] On changing the units of 𝑐 in a more convenient form, we have 𝑐 = 0.3 km/microsec. On substituting 𝑥′=15 km and 𝛽=0.999, as taken in sub-section ‘B’ above, the expression for 𝑡 becomes as
