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.
How do you find earth's circumference?
by going arround the earth
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?
3.229 miles/hour
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?
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
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.
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.
Where is the 0 degree latitude line located?
The widest circumference of Earth (the Equator).
Using 6200 miles as the circumference of the earth at his latitude determine the average speed in miles per hour?
6200 miles per day = 258.3 miles/hour.
What is the distance around the earth at 70 degrees north latitude?
The distance around the earth at forty degrees South Latitude would be 19,049 miles. The circumference of Earth at the equator is 24,902 miles.
What is distance in miles at 0 degrees Latitude around the Earth?
Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km) (from about.com); 0 degrees latitude is the equator.
In the movie Around the World in 80 Days a man accepts a bet and circumnavigates the earth in you guessed it 80 days Using 6 200 miles as the circumference of the earth at his latitude determi?
The average speed is [ 6,200 miles per 80 days ].In somewhat more common units, the speed is-- 3.23 miles per hour-- 4.74 feet per second-- 5.20 km per hour-- 1.444 meters per second-- 8,680 furlongs per fortnight(all rounded)
What is the average of distance?
The Earth is about 8000 miles in diameter, so use the formula for circumference of a circle. The average circumference of our planet Earth is approximately 8000 x pi, or 25,133 miles.
What is the northernmost line of latitude?
The equator is the longest line of latitude as it is located at the circumference of Earth, and the circumference of Earth is always the longest compared to anywhere as the theory is the same of the circumference of a sphere.
What did Erastothenes discover?
Amongst other things, that the Earth was round, a system of latitude and longitude, he calculated the tilt of the Earth's axis, he also calculated the circumference of the Earth.
