Number crunchers: 30. 65. 80. 54.?

The average is 57.25. The median is 59.5. If these are coordinates, they would have to be degrees and decimal degrees. With both degrees positive, this is in the Chinese Himalayas, about 30km from the border with India, a bit northwest of Nepal. Making the 80 negative puts us about 60km offshore from Jacksonville, Florida. With both sets of degrees negative you are about 400km WNW of Santiago, Chile. And making the 80 positive again is waaay out in the middle of the Indian Ocean, roughly halfway between Madagascar and Australia.

So! What is your Question??
What do you want done with that list of numbers??
