Question of the Week

I thought it was a good question but only got one response, so I will redo it.

If 40% of all cats believe this false statistic, and
20% of all rocks believe this false statistic,

which is stupider, cats or rocks?

Question of the Week: if you get on a train…

If you get on a train traveling 80 miles per hour north, and I get on a train traveling 314 kilometers per hour southwest, and I shout to you after we have both been traveling for 2 minutes, how long will I have to wait to hear a return shout? Assume that you respond 5 seconds after you hear me. Also assume that we are in a vacuum, because sound travels fastest there.
