equals a plus 3
O v e r space t h e space n e x t space apostrophe c apostrophe space s t o p s space a n space a v e r a g e space o f space apostrophe b apostrophe space p a s s e n g e r s space g e t space i n.
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
I f space o n e minus t h i r d space p a s s e n g e r s space g e t space d o w n space a t space t h i r d minus t o minus l a s t space s t o p comma
t h e n space t w o minus t h i r d space o f space t h e space p a s s e n g e r s space a r e space s t i l l space i n space t h e space b u s
2 over 3 cross times open parentheses a plus 3 plus b c close parentheses equals fraction numerator 2 open parentheses a plus 3 plus b c close parentheses over denominator 3 end fraction
a v e r a g e space n u m b e r space o f space p a s s e n g e r s space g e t t i n g space d o w n space o n space t h e space l a s t space t w o space s t o p s
equals fraction numerator N u m b e r space o f space p a s s e n g e r s space l e f t over denominator n u m b e r space o f space s t o p s end fraction
equals fraction numerator 2 open parentheses a plus 3 plus b c close parentheses over denominator 3 end fraction cross times 1 half equals fraction numerator a plus 3 plus b c over denominator 3 end fraction end style
