You could say 17-year-old Feliks Zemdegs is pretty good at solving Rubik's Cube. The Australian teen turned in an impressive time of 7.36 seconds at the Rubik's Cube World Championship in Las Vegas. 575 people from 37 countries competed for the title at the three-day event.

7.36 seconds isn't exactly the world's fastest time. Dutchman Mats Valk holds the world record of 5.55 seconds, but he came in second to Zemdegs in this year's competition.

How fast can you solve Rubik's Cube? I've been working on it since 1974 when it cam out, and still haven't made much progress.
