You can think of this situation as one of the cars
traveling at the sum of their speeds and the
other car standing still.
The equation is:
+192+=+%28+r+%2B+r+%2B+10+%29%2A+%281+%2B+36%2F60%29+
+192+=+%28+2r+%2B+10+%29%2A1.6+
+192+=+3.2r+%2B+16+
+3.2r+=+192+-+16+
+3.2r+=+176+
+r+=+55+
+r+%2B+10+=+65+
The average speeds are 55 mi/hr and 65 mi/hr
