Should we use plural or singular for a fraction of a mile?
I'm working on a website that displays distance to various locations to the nearest 1/10 mile. One of the developers (a non-native speaker) asked me an interesting question: If the distance is 1.0 mile(s), is that singular or plural? Clearly, anything other that 1.0 is plural, but is it:
1.0 miles away
1.0 mile away
The first option sounds more correct to my ear, but the voice of my elementary school language arts tells me that the latter option is correct.
Edit: Added the word 'away' to the example. It doesn't change the question, but might provide clarity for the answer. Also, regarding numbers between 0 and 1, after more thought, I'm not sure that the answer is as clear as I originally thought. See http://mathforum.org/library/drmath/view/57224.html.
