A couple years ago many of you may have seen or heard the video of the man who asked his wife this mathematical question:

 

If you traveled 80 miles at 80 miles per hour, how long would it take to finish your trip?  The video above shows that she couldn't figure it out.  Well turns out she isn't the only one.

The video below surfaced recently out of Ireland, with 2 sisters having the same discussion about the same math problem.

This one is funny because, finally after a few minutes her very Irish mum gets fed up with her stupidity and starts yelling at her for being so dumb.

(Video may be offensive to some)
