Around antarctica

We know that from North Pole to South Pole, distance is around 20 000km. If we use the same measurement on flat earth from North Pole to and furthest distance on “South”, it looks like the map below.

Flat earth map with red line (20kkm) and green circle.

Now when we measure a circle we use following:

RED = 20.000km (r)

d = 2r

p = 2πr

p = πd

GREEN = p = πd = 125 663,7km

Based on calculations, flat earth circle is 125 663,7km long.

What have been calculated on globe, is that the circumference of the Antarctic circle is roughly 16,000 kilometres. https://books.google.fi/books?id=Swr9BTI_2FEC&pg=PA115&redir_esc=y#v=onepage&q&f=false

Known fastest time around antarctica is around 43 days. It is 173km/day, if we divide 16 000 km with 43 days. But as we can see from the recorded world record, it doesn’t go around the antarctica circle, it is going even further. So, the speed per day could be closer to 200-220km/day.

Now, if we are going to calculate how long it would take to go around flat earth (or technically sail next to ice wall), we can take out around 600km from calculated flat earth circle that was 125 663,7km. This would mean that if we travel 200-220km/day (currently the fastest time/day), then we divide 125 063km with 200km/day or with 220km/day. With 200km/day, it would take 625 days and with 220km/day it would take 568 days to go "around" the flat earth. Those are much longer journeys than the world record.

If this doesn’t prove anything, please dear flat earthers, do correct my calculations.

Oh, and if someone is saying “Well google maps is lying”. Go and check your own route, walk, drive or crawl it and check the distance by yourself. I bet they are close to each other.

And here is example measure from Nuorgam to Port Elizabeth. Distance is 16 335km (this is just a reference for the 20 000km distance so that it is possible to achieve 20kkm, if sea distances are also calculated).
