Re: Finding distance of Latituded...

[roger haar <haar@soliton.physics.arizona.edu>]

Delissa,

	Assuming that the two cities have the same longitude, one 
finds there separation by taking the circumference of the earth 
( = 2 pi 12756km ) times the faction of 360 degrees that separates
the cities latitude.  

	In your example this is :

	2  X 3.14 X 12800 km X ( 44:30:30 - 42:00:00 ) /360

   =     	80,000    km X ( 2 + 30/60 + 30/36000) /360

 
	I hope this helps
Thanks
