----------------
Going in opposite directions ---> the speeds are added.
d = r*t
t = d/r

Think of this as Anne standing still and Pat
walking at the sum of their speeds.
Let +t+ = the time in hrs it takes
for them to meet
+15+=+%28+3+%2B+2+%29%2At+
+t+=+15%2F5+
+t+=+3+
They will meet in 3 hrs
---------------------
check:
Anne's equation:
+d%5B1%5D+=+3t+
+d%5B1%5D+=+3%2A3+
+d%5B1%5D+=+9+
-------------
Pat's equation:
+d%5B2%5D+=+2t+
+d%5B2%5D+=+2%2A3+
+d%5B2%5D+=+6+
+d%5B1%5D+%2B+d%5B2%5D+=+9+%2B+6+
+d%5B1%5D+%2B+d%5B2%5D+=+15+
OK
