Captain Jean-Luc is piloting the USS Enterprise XXIII at constant speed v = 0.830 c. As the Enterprise passes the planet Vulcan, he notices that his watch and the Vulcan clock both read1:00 P.M. At 3:00 P.M., according to his watch, the Enterprise passes the planet Ender.
If the Vulcan and End or clocks are synchronized with each other, how much time will have passed on End or when the Enterprise passes by?
