Phileas
According to a book written by Jules Verne in the 19th century, Phileas Fogg travelled around the world in 80 days. The Breitling Orbiter 3 balloon, which first circled the Earth without landing in 1999, was in flight for 19 days. The International Space Station orbits the Earth in 1 hour and 32 minutes. Their respective orbital distances were 60,000 km, 43,000 km, and 42,500 km. What were the average speeds of each?
