Trek also slows down warp at the speed of the plot. TOS established in 'That Which Survives' that 1701 can travel 990.7 light years in 11.337 hours, or 87.39 light years per hour.Or it's just Trek's Speed of Plot thing, which has been going on since day one![]()
At this speed, 70,000 light years shouldn't be too bad for Voyager and Voyager should have reached Earth in about 33 and a half days
