Mary's time: +x+ min
James time: +x+%2B+20+ min
Phillip's time: +2%2A%28+x+%2B+20+%29+
--------------------------
Time for James and Phillip:
+x+%2B+20+%2B+2%2A%28+x+%2B+20+%29+
+x+%2B+20+%2B+2x+%2B+40+
+3x+%2B+60+
---------------
+t+=+x+%2B+3x+%2B+60+
+t+=+4x+%2B+60+ is the time in
minutes for all three
