1. ## Help with calculating coordinates.

I have an issue on how they got these answers.
The first two digits can only reach 60. I think this is where I get them wrong.

54°35'N - 67°34'N Correct Answer: 12°59'N
27°25'N - 07°44'N Correct Answer: 19°41'N

Any help would be greatly appreciated.

Thanks

for the first one, I think you mean ...

$\displaystyle 67^\circ 34' - 54^\circ 35'$

"borrow" a degree ... $\displaystyle 1^\circ = 60'$

$\displaystyle 67^\circ 34' = 66^\circ 94'$

now subtract
