Homework Inquiry Question: “Is the Earth a perfect sphere? Justify your answer.”
Answer: No. Because the distance of the equator and the distance of the else place is different.
Measured value: 150.23km (between 31°, 121°19′39.86″ and 29°, 121°19′39.86″)
Accepted value: 39900km (pass through the Arctic and Antarctic)
40075.7km(pass through the equator)
Calculation 1: Percent error=|39902.4-39900|/39900=0.06%
Calculation 2: the rate of travel=39900/80=498.75(km/day)
the days will take=39900/100(km/day)=399(days)
It is quicker to take the polar route. Because the circumference measured around equator is greater than the circumference measured around the polar.
