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?

Final Answer:

v1 =  31.25 km/h
v2 =  94.3 km/h
v3 =  27717.4 km/h

Step-by-step explanation:

s1=60000 km s2=43000 km s3=42500 km  t1=80 24=1920 h t2=19 24=456 h t3=1:32=1 hr 32 min =1+6032=1.5333 hr1.5333  v1=s1/t1=60000/1920=31.25 km/h
v2=s2/t2=43000/456=94.3 km/h
v3=s3/t3=42500/1.5333=27717.4 km/h
