The question asks to find the difference in longitude between atlanta and san francisco.
00:04
And in the textbook, there's a table that tells me what the longitude are.
00:08
So atlanta, i'm going to call a, and it's at longitude 84 degrees, and then 23 minutes.
00:16
So what i'm going to do is i'm going to divert that into degrees.
00:19
So it's 84, and then this guy is 23 divided by 60, and that gives you 0 .383 repeating.
00:29
So when i convert this, it becomes 84 plus that.
00:33
So 84 .383 repeating degrees.
00:38
Then san francisco, which i'm going to just label sf, is 122 degrees and then 25 minutes.
00:46
So again, i'm going to do the same process.
00:47
I'm going to convert 25 over 60.
00:52
And when i do that, 25 divided by 60 is 0 .41 and then six repeating...
