EN: a 5 minutes' walk / a 5-minute walk
5 minutes walk
I'm editing a text and I'm about to amend this to "5-minute walk". But because the author of this text has a good command of English, I wonder: is "a 5 minutes walk" also valid?
Could someone confirm, or point me to the right place to check on this?
