Question 557185
You live in Marquez, New Mexico, which has approximate latitude-longitude coordinates of (35N, 107W) and your friend lives in St. Paul, Minnesota, with coordinates (44N, 93W).
:
If we treat it like it is a flat surface, (not sphereical) we can us the mid point formula; 
m.p. = {{{((x1+x2))/2}}}, {{{((y1+y2))/2}}}
Assign the values as follows
x1=107, y1=35
x2=93,  y2=44
:
m.p. = {{{((107+93))/2}}}, {{{((35+44))/2}}}
m.p. = {{{(200)/2}}}, {{{(79)/2}}}
M.p. = 100, 39.5
:
They should meet at 39.5N, 100W
