You can put this solution on YOUR website!
Ill call the terminals A and B
I'll call the one-way trip
either
AB ( to B )
or
BA ( B to A )
--------------
The wait times are
wA ( wait at A )
wB ( wait at B )
---------------
The sequence could be:
wA
AB
wB
BA
wA
AB
wB
BA
wA
AB
etc.
----------
If +n+ = number of one-way trips.
I can say:
+6%2A60+=+%28+10+%2B+40+%29%2An+
+50n+=+360+
+n+=+7.2+
The bus can make 7 one-way trips in 6 hrs
