How long does it take to travel around the world?

  1. The circumference of the earth is 40 thousand kilometers, and the speed of a 747 airliner is about a thousand kilometers per hour. If you were to travel in a 747 then you could do it in 40 hours, or about 1 day and 16 hours, assuming you had enough fuel on board. I’ve flown from London to Australia and it’s taken about 20 hours, so this figure seems about right!
