Question

How far is a geographic second?

Answer 1

The distance between minutes of latitude is approximately 1.15 miles. There are 5280 feet in a mile, so there are 6072 feet in 1.15 miles. 1/60th of that is 101.2 feet.

Answer 2

Answer:

At the equator, one second of longitude is about 30.480 meter or 100 feet and The distance between minutes of latitude is approximately 1.85 km (1.15 miles)

Explanation:

There are 60 minutes in a degree and 60 seconds in a minute. In other words, a second is 1/60th of a minute and a minute is 1/60 of 1 degree. As we know, there are 360 degrees in a circle. The distance will depend if you are measuring latitude or longitude.

• The distance between minutes of latitude is approximately 1.85 km (1.15 miles). There are there are 1000 meter in a km or in other way if we talk about feet, there are 5280 feet in a mile, so there are 1850.746 meters in 1.85 km or 6072 feet in 1.15 miles. 1/60th of that is 30.846 meter or 101.2 feet.  

• At the equator, one second of longitude is about 30.480 meter or 100 feet. This slight difference is because lines of latitude are parallel and almost equidistant but lines of longitude converge at the south pole and north pole.
