(1)It took me five days to walk from here to there. :D
(2)It took a five day walk from here to there. :D
(3)It took five days' walk from here to there. :(
(4)It took five days walking from here to there. :(
In (3) 'five days' functions as an adjective, so the apostrophe is not required. As a noun: five-days of a walk, 'of a' is required. In (4), an infintive is required: "It took us five days to walk from here to there." As a modifier -ing is OK: "It took us five days, walking from here to there, to get there.
All the best, :D |
