It would take a jet 24 hours to travel the circumference of the earth if it travelled at a speed of 2,213.32716 km per hour.
If it's not true then blame it on d(3.14145926) !

Okay. You think I'm mad because in universitys they only approximate Pi to 3.14159. So what? Isaac Newton did calculations to 50 decimal places!

I did a more accurate calculation answerer #2. In Paris when they were making the new metric system they calculated that 10,000,000 meters would be enough to go from the North Pole to the equator passing from a line through paris. Using the equation 2 x Pi x r (or D x Pi as I did it) I calculated the circumference of the earth. I then divided this by 24,000 to get my answer.

Please note that I am not crazy enough to do the madly accurate 62,831,852 meters divided by 23 Hours 56 Minutes and 9 seconds.

D'oh! I've been acting like Pythagoras! The earth is not a disc and it moves as well!

Actually I did use 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679....
That was just a typo.

Sounds good to me. The Earth is about 40,000 km around the equator. You plane covers approximately the same distance.

its not true and the problem isn't Pi. the problem is whatever value you have taken r to be (I'm assuming you put the numbers into your calculator correctly). now i only used the pi button on my calculator so I'm probably a little out but i make it 1675.5 km/hour. the earths radius is 6400 km not the 8500 km or so you seem to have used. I'm not sure where you got this figure from but it is wrong. badly wrong. hope this helps in some way.

In Miles the earths circumfrence is 25046 (1.6 km to a mile) divide that by 24 hours and that would give you an average speed of 1043.6197916' MPH or 1044MPH to round it up

The circumference of the Earth is approx 40,075km. If you travel at 2,213km/h you will travel 53,120km.
To make the journey in 24hrs I would think you need t travel 1,670km/h

I don't know how to change KM to MPH but if it were MPH then it would be 2490 miles per hour that it would have to travel, the circumference of the earth is 24,900 miles

globe radius = 6400km, so if i'm to travel the circumference of the earth in 24h, my jet must do 1675.516km/h
you pi is wrong too. it equals to 3.1415926 - not 3.14145926

If you flew West it would only take you only 1/4 as long to get to the same place you left from, as the world would turning beneath you, than it would if you flew East.
