No one knows the answer to that question. I have seen two videos of people solving a 3x3x3 in less than twenty seconds - using twenty different methods. Speed depends on things such as how fast a person turns and how much they know.
Having said that, there are three methods that are widely used. These methods have the potential for times far below twenty seconds.
1. - CFOP
Feliks Zemdegs uses this method. He consistently gets times below ten seconds.
For more information about this method, search around the Internet. YouTube, specifically, has many videos, including tutorials. I mention some good videos in this post
2. - Roux
Alexander Lau uses this method. He also consistently get times below ten seconds.
Search around for this method too; YouTube has videos and tutorials. This page
has information in words and links to videos for learning Roux.
3. - ZZ
Phil Yu uses this method. He mainly uses it for one-handed solving. He has done solves under ten seconds using this method (using both hands).
For information about this method, there is this written tutorial
and this video one
You will not waste your time pursuing any of these methods. Look into each one and try them. Then, whichever one you like using more, use it.
If you have any more questions, just ask. Enjoy cubing beyond the seven steps!
