In the Voyager episode Scorpion Part 1 (season 3 finale) our heroes are headed to a destination that is 5.2 light years away. Captain Janeway orders Paris to set a course and move at warp 2. According to it's Memory Alpha page, warp 2 is barely 10 times the speed of light, at least in the TNG universe. The values in the Voyager universe appear to be similar to that.
Thus, we would expect to take about 6 months to reach something 5.2 light years away going 10 times the speed of light. Yet it's obvious they get there in a very short period of time.
How is this reconciled in universe?
