Answer:
160 degrees
Explanation:
The latitudes are measured in degrees. The basis on which the measuring takes place are the parallels, which are lines parallel to each other, going both north and south of the Equator, up to the North Pole and down to the South Pole.
There are 180 degrees of latitude in total, but they are divided into 90 degrees North, and 90 degrees South.
If we move directly south from the North Pole, and reach the 70 degrees North mark, it means that we have passed 20 degrees from the North Pole to that particular place. In order to get to the Equator we have 70 more degrees to pass, and to reach the South Pole, 90 more degrees from the Equator. 70 degrees to the Equator plus 90 degrees south from the Equator makes 160 degrees, which is the amount of degrees we'll need to pass to reach the South Pole.
