Answer:
(39.77°N, 102.07°W)
Step-by-step explanation:
Given Rose' coordinates as (47.03°N, 122.53°W) and her friend's coordinates as (32.5°N, 81.6°W), to determine the coordinates of the midpoint we have to add together the x and y coordinates respectively and divide the results by 2.
x-coordinate of the midpoint will be;

y-coordinate of the midpoint;
