Santa has 31 hours of Christmas to work with, thanks to
different time zones and the rotation of the earth, assuming
travels east to west (which seems logical). This works out
822.6 visits per second. This is to say that for each
household with good children, Santa has 1/1000 th of a
park, hop out of the sleigh, jump down the chimney, fill the
stocking, distribute the remaining presents under the tree,
whatever snacks have been left, get back up the chimney, get
back into the sleigh and move on to the next house.
that each of these 91.8 million stops are evenly distributed
around the earth which, of course, we know to be false but
the purposes of our calculations we will accept, we are now
talking about .78 miles per household, a total trip of 75.5
million miles, not counting stops to do what most of us do
least once every 31 hours, plus feeding, etc.
That means that Santa's sleigh is moving at 650 miles per
3000 times the speed of sound. For purposes of comparison,
fastest man-made vehicle on earth, the Ulysses space probe,
at a poky 27.4 miles per second - a conventional reindeer
run, at tops 15 miles per hour.
