The first date of landmark is 34°44,24 ,43 E
29° 44,38,76N
So the difference is 5°
The distance between two landmark is 374.15km
C/374.15=360/5=43353.7961472≈4335380
Percent Error = 3278.096/40075.7= 0.0817= 8.2%
The earth is not a perfect sphere.
The first method that I got to the circumference is keeps the longitude constant and change the latitude. When I use change another variable that keep the latitude constant and change the longitude I can know result is completely not similar. So I think the earth is not a perfect sphere
Calculation
80day=80*24=1920hours
C/80=40075.7/80= 500.946 ≈501
So if everyday keep the speed of 501km/day 80days can navigate the earth
If the rate of 100km/h is the average speed the one day is 100*24=2400km/day
C/2400=40075.7/2400=16.698≈17
So seventeenth days can circumnavigate the earth of circumference.
Because 501 is bigger than 17 so it is definitely quicker.
