Brain Teasers
Tom & Jerry
Tom is chasing Jerry again! Jerry can run at 1 meter/sec, but Tom can run at 1.5 meter/sec.
Tom, being a stupid cat, runs into a 3 meter long sofa and takes 3 seconds to wriggle out. Jerry's mouse hole is 2 meters away from the other end of the sofa.
If Jerry runs under the sofa 1 second after Tom gets stuck, and Tom runs over the sofa to catch Jerry, will Tom catch Jerry?

Hint
Simple MathsAnswer
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.
