Of those, about 700,000,000 celebrate Christmas (and make the nice list!). With an average of three children per house, that\u2019s a whopping 233,000,000 stops that Saint Nick has to make! Now bear with us\u2026<\/p>\n<p>If those stops are distributed evenly around the world, with a total surface area of 317,000,000 miles, each stop is 0.91 miles apart, making a total of 212,030,000 miles that Santa has to travel.<\/p>\n<p>Because of the time differences across the globe, Santa has approximately 32 hours to complete his trip, maximising the night time (and sleeping children) available. Using <strong>speed = distance \u00f7 time, <\/strong>we can then work out that he has to travel at 6,650,807.72 mph!
