You can put this solution on YOUR website!
Let +d+ = distance the M.S. has traveled
+2184+-+d+ = distance A.E. has traveled
------------------
Equation for M.S.
(1) +d+=+97%2A12+
Equation for A.E.
(2) +2184+-+d+=+85%2A12+
-----------------------
(1) +d+=+1164+
and
(2) +2184+-+d+=+1020+
--------------------
The M.S. has traveled 1164 mi when they meet
check:
+1164+%2B+1020+=+2184+
+2184+=+2184+
OK
