It depends upon how you are traveling and how far you have to go. At the North Pole or South Pole, you could go "around the world" in a few seconds.

But to travel completely around, as in circumnavigation around the equator, which is about 24,902 miles would take

  • about 90 minutes in an orbiting spacecraft
  • about 5.5 hours at the speed of the X-15 (4500 mph)
  • about 11.5 hours in an SR-71 (2200 mph, but it wouldn't have the fuel for it)
  • about 40 hours in a 747, such as Air Force One, which could refuel in flight (600 mph)
  • about 600 hours or 25 days in a fast boat (40 mph)

Cargo ships and oil tankers, even using the Suez and Panama Canal, would take about 45 to 60 days to circle the globe, although much less if (as above), they travelled south of Africa, South America, and Australia through the Southern Ocean.
