Tom and Jerry

Jerry beats Tom (Again!)
Jerry needs to run 6 meters, (added the extra second before the sofa), while Tom has to run 9.5 meters (added the seconds taken to wriggle out)
6/1 = 6 seconds
9.5/1.5 = 6 and 1/3 seconds.
Jerry will beat Tom by half a meter or 1/3 of a second to Jerry's hole.
