The new latitude is given by adding the 55° flown to the original latitude, which is 17° S, or -17°; this gives -17+55=38°.
Explanation:
The equator is taken as 0°, going north is positive and going south is negative. So 17° S should be taken as meaning -17°. Flying north 55° means I should add 55°. That gives the answer above.
