When talking about "one and a half" of any object, do we use the subsequent noun in plural or just singular? I'm aware that "A minute and a half" is also correct but I'm looking for the specific "One and a half"-construction here.
So for example, which of the below phrases is correct?
You're one and a half minutes late!
You're one and a half minute late!
Is there any difference when using the phrase as an adjective like so: "One-and-a-half-minute recipe"?
