I choose Shanghai (31°13'49.41"N 121°28'25.33"E) and a unknown place (11°13'49.41"N 121°28'25.33"E) to be two point I need to put into formula to get the circumference of the Earth. And I get 39861.36km
Calculation1: |39861.36km- 40075.7km|/ 40075.7km= 0.53%
Calculation2: 40075.7km/ 80days≈501km/days
40075.7km/ 100(km/days)≈401days
Is the Earth a perfect sphere?

-A: No, it isn't (Because god don't know geometry so he don't know how to draw a perfec sphere). That's kidding , I think because diastrophism or some other reason, so
