S o space t o t a l space n u m b e r space o f space p a s s e n g e r s space i n space t h e space apostrophe c apostrophe space s t o p s
equals a v e r a g e space cross times n u m b e r space o f space s t o p s equals b c
S o space t o t a l space n u m b e r space o f space p a s s e n g e r s space d u r i n g space t h e space j o u r n e y space equals space a plus 3 plus b c
