What is the distance in nautical miles between 42N 115W and 42N 116W?

Question

I think that the calculations being done in a legacy program I'm working on are incorrect. A range and bearing tool in the program says that the distance between 42N 115W and 43N 115W is 60 nautical miles. I'm pretty sure that's correct.

It also says that the distance between 42N 115W and 42N 116W is 44.7 nm. Is that right?

Answer 1

Using the WGS-84 Earth model:

42 N 115 W to 42 N 115 W is 59.980024 nat. miles
42 N 115 W to 42 N 116 W is 44.735578 nat. miles

Answer 2

you are correct........and thanks to the other poster for the niffty link!......a degree of Latitude ( Ie 42N to 43N. or 1N to 2 N is, by definition, 60 nautical miles

A Degree of longitude will vary from 60 nautical miles at the equator to nothing at the poles........

also, EArths circumfrence of 21, 600 miles divided by 360 degrees gives 60 nautical miles; a degree of 60 minutes gives ......a mile a minute!

do your own homework. what is wrong with you kids these days? You'll never learn anything if you don't try. then you'll be a slacker who's 35 and working at McDonald's flipping burgers because you didn't challenge yourself enough to make anything else of yourself.
