Should we use plural or singular for a fraction of a mile?

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!

or

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"?

Solution 1:

When you say "one and a half" you are referencing more than one minute, so you must use the plural form "minutes".
