Tuesday's Teaser: New Years Day Edition
The average person can walk at a rate of 4 miles per hour
(mph). At this rate, how long would it take you to walk around the world at the
equator? The answer should be in months,
days, and hours, rounded to the nearest hour.
Example: 5 months, 14 days, 12
hours. 
First five correct answers share the 50 bonus points.
Special double bonus: Last week's Christmas teaser contained a fundamental flaw. Not that Santa was lying, he's just old. But the story could not have gone down the way he wrote in his book. Tell me the flaw, and nab 10 exxxtra points. Offer valid until 1/7/13.

Tuesday's Teaser: Christmas Edition
*As Santa prepared to deliver the last of his packages down under in Sydney, Australia, he noticed two small boxes at the bottom addressed to: "Bambino, Rome Italy". Realizing that the boxes had been misplaced and that he only had 4 hours before the Bambino would wake up, Santa strapped a pair of Nike Air Max Hyperaggressor's on each reindeer and sped towards Rome. Exactly 4 hrs. later, Santa delivered the boxes and headed home to Mrs. C.
Find the distance (in miles, rounded to the nearest hundred) between Sydney and Rome, then calculate Santa's average speed during his trip.
First five correct emails receive 10 bonus points and something extra in their stocking.

Should Have Been...
Sorry gang, I said not to do the Rates.5 topic when it should have been the Units topic. Anyone who has tried the Units topic knows what I mean. Rates.5 is very do-able. Let's do that one instead of Units.
You will have until Wednesday for full credit.
