I've done a search but i can't seem to find what i want.
How would you calculate the distance (say)from London to New york?
1 deg = 60 mins
1 min = 1nm that way.
I've got a book which says
1 min = 60 mins
and
1 min = 1 nm
but on a map i have, 1 hour is 15 degrees. And it works out that NY is about 75 degs from london.
What's going on? it seems as though 60 mins are different to 1 hour time, is this true?
