the average of how old the "newest" file is in a table?

Hi,
How do I get the "average of HOW old the "newest" file is" using Oracle from a Table? any idea??
let say for example I have a table called A and I want to know HOW OLD is the NEWEST FILE in that table!!

Just order by creation, which I'd assume is the default. The just grab the first result. Probably best if you use a table to track the date it was created, then it's easy. Order by that, then display that on the result.

I have no idea why you're calling this an "average" and saying "newest", since the two terms are quite different.
