You can put this solution on YOUR website!
Think of one of them moving at the sum of their
speeds and the other one standing still
Let +t+ = the time in hours it takes for them to meet
---------------
+30+=+%28+12+%2B+8+%29%2At+
+30+=+20t+
+t+=+1.5+ hrs
They will meet at 1:30
--------------------
check:
Mike's equation:
+d%5B1%5D+=+12%2A1.5+
+d%5B1%5D+=+18+ mi
and
+d%5B2%5D+=+8%2A1.5+
+d%5B2%5D+=+12+
+d%5B1%5D+%2B+d%5B2%5D+=+18+%2B+12+
+d%5B1%5D+%2B+d%5B2%5D+=+30+ mi
OK
