The Borg are coming. You’re joining the fleet at Wolf 359 to try and stop them. How fast do you need to go to get there in time?
First, find out how fast you need to go in terms of the speed of light:
Second, convert that into warp speed with Wolfram|Alpha’s new converter:
Wolfram|Alpha determines you would need a warp factor of 7.818 to reach Wolfram 359 within 3 days.
As to what happens when you get there, we can’t help you with that. Best of luck.
