Answer:
(39.77°N, 102.07°W)
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;
[tex]\frac{47.03+32.5}{2}=\frac{79.53}{2}=39.77^{\circ}N[/tex]y-coordinate of the midpoint;
[tex]\frac{122.53+81.6}{2}=\frac{204.13}{2}=102.07^{\circ}W[/tex]
