What is the average speed in miles per hour if a man circumnavigates the earth in 80 days using 6200 miles as the circumference of the earth at his latitude?

6200 /(80*24) = 3.23 miles per hour on average; a good walking speed. However, nobody can walk 24 hours per day. Especially not wearing a parka, mukluks and snowshoes.
So 6200 /(80*8)= 9.69 miles per hour, traveling for 8 hours per day, every day. An easy pace for an airship, since much of that distance will be over icy water or snow.
The problem only obliquely refers to the latitude, which I did not calculate. But it would be pretty high.
Oh, what the heck. The calculation for latitude is (approximately) 25000*cos(90), so 6200=25000*cos(x), or 6200/25000 = cos(x), so x= 75.6 degrees.
This calculation is based on the Earth being a perfect sphere, which it is not - but the difference isn't substantial. And the equatorial circumference of the Earth isn't exactly 25,000 miles, but these numbers are "close enough".

Which line of latitude is the longest?
The locus of all points of zero latitude ... sometimes also known as the "Equator" ... is the longest parallel of constant latitude. It's length is the equatorial circumference of the earth ... roughly 24,900 miles (40,073 km) .
What is the circumference of the earth in inches?
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
What is the distance of the circumference of the Earth?
Best guess for Earth Circumference is 24,900 miles (40,080 km)
How many miles are in a minute of longitiude or latitude?
- One minute of latitude is one nautical mile (1.15 miles, 1.85 kilometers)- One minute of longitude at the equator is also one nautical mile, but decreases as you move toward the poles.---You can find this by taking the Earth's circumference and divide it with number of minutes. Earth's circumference (the length of equator) is 40075.02 km.40075.02 / 360 / 60 = 1.8553 kmOne minute of longitude on equator is 1.8553 km. Please note - on equator (i.e. on 0 degree of latitude)!Because the length of parallels decrease toward the north or south pole, the length (in km or miles) of minute of longitude differs for different latitudes. For example on polar circle (66°33'38" south or north) one minute of longitude is only 1.0035 km.For latitude it's simpler - the length of all meridians are the same.Take Earth circumference (the length of meridian) is 40007.86 km. Please note - Earth equatorial circumference differs from meridional, because Earth is not a sphere.40007.86 / 360 / 60 = 1.8522 kmOne minute of latitude is 1.8522 km.For common life it's much to easier consider Earth spherical and use nautical miles.One nautical mile is 1.852 km and it's approximately the length of one minute from meridional circumference.
What is the circumference and diameter of Earth?
The diameter of Earth at its equator is 12,756 km and its circumference is about 40,075 km.
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
You can use the relationship between the circumference of the Earth and the circumference of the smaller latitude to calculate the Earth's circumference. Multiply the circumference of the smaller latitude by the cosine of the latitude. This will give you the circumference of a circle at that latitude, which can then be used to estimate the Earth's circumference.
What is the circumference of the earth at 30 degrees latitude?
At 30 degrees latitude, the circumference of the Earth can be calculated using the formula for the circumference of a circle: C = 2πr * cos(latitude), where r is the radius of the Earth. Taking the average radius of the Earth to be about 6,371 kilometers, the circumference at 30 degrees latitude would be approximately 29,792 kilometers.
In the movie Around the World in 80 Days a man accepts a bet and circumnavigates the earth in 80 days. Using 6200 miles as the circumference of the earth at his latitude determine t?
The man would need to travel at an average speed of approximately 78 miles per hour to circumnavigate the Earth in 80 days. This calculation is based on the assumption that he travels continuously without delays or stops.
A man accepts a bet and circumnavigates the earth in 80 days Using 6200 miles as the circumference of the earth at his latitude determine the average speed in miles over hour?
To find the average speed, we divide the total distance by the time taken. In this case, the man circumnavigated the Earth in 80 days, which is 24 hours/day * 80 days = 1920 hours. The total distance traveled is 6200 miles. Therefore, the average speed is 6200 miles / 1920 hours ≈ 3.23 miles per hour.
What is the average circumference on earth?

What is the distance around the world at forty degrees north latitude?
If the Earth's equatorial circumference is 24,900 miles, thenthe circumference at 41° north latitude is 18,792 miles.
What is the distance around the earth at 70 degrees north latitude?
At 70 degrees north latitude, the Earth's circumference is smaller compared to the equator. The distance around the Earth at this latitude is about 16,029 kilometers (9,967 miles).
What is the circumference of earth at London?
The circumference of Earth at the latitude of London (approximately 51.5 degrees N) is about 40,008 kilometers (24,901 miles).
Where is the 0 degree latitude line located?
