I am doing my business course assessent and the teacher gave us a case study about a coffee shop. The coffee has a policy of serving within 2 minutes. Of course, in my answer, I can write "waiting time of 2 minutes" (or any other variation).
However, a question came accross my mind. Is it possible to use apostrophe after the words minutes, seconds, etc., as we do with years? Following the same structure of "2 years' experience", can I say the café has a '2 minutes' waiting time policy". Is this sentence correct?
What about "2-minute waiting time policy"? or "2-minutes' waiting time policy".
I am quite confused about which sentence would fit better.
Thanks
