Final answer:
Place A and Place B are 100 degrees of latitude apart since the absolute values of their latitudes add up when considering one is north and the other is south of the equator.
Step-by-step explanation:
The number of latitude degrees between Place A (60°N, 75°W) and Place B (40°S, 75°W) can be found by considering their positions relative to the equator.
Since latitudes range from 0° at the equator to 90° at the poles, and are designated as north (N) or south (S), we can calculate the difference by adding the absolute values of the latitudes of both places. In this case, the calculation is as follows: 60° (north) + 40° (south) = 100°. Therefore, Place A and Place B are 100 degrees of latitude apart.
