Trivia: One of the Ferengi, Ulis, is played by Ethan Phillips. Phillips played Neelix in "Star Trek: Voyager." In S3 E5 of Voyager, "False Profits", Neelix disguised himself as a Ferengi.
Trivia: Trip tells Malcolm, "if I remember my honors biology course correctly, your hair and nails keep growing for quite a while after you're dead." However, this is a myth and would never be taught in any biology class, especially in the future. Nothing keeps growing after you're dead, as the skin dries out, and the body decomposes, the skin retracts and just makes the hair and nails look longer. This is more likely a mistake, but since it's possible Trip isn't a biology expert, forgot his honors biology, or is just teasing Malcolm, it should be noted as trivia.
Answer: Warp factor has always been inconsistent and hard to pinpoint, or there's too many episodes that contradict the conversion rates. Changes were made in converting warp factor into actual speed between TOS and TNG. It seems ENT reverted back to using TOS method, which is "warp factor cubed" equals how many times the speed of light they traveled. So warp 4.5 means 91.125 times the speed of light (c). Although in "Broken Bow", with the travels from Earth to Neptune and back in about six minutes means warp 4.5 is about 86*c. However, in "The Expanse" episode, warp 5 was 200*c (instead of 125). 1 ly at 91.125*c is about 4 days, but 100 ly would be 400 days.
