Although the problem's composer points that the car and the bus move in opposite 
directions, this fact does not matter, does not play any role and, therefore, 
does not make any sense in this problem.



It is EXCESSIVE and is NON-NECESSARY; so, for a reader, it is better to ignore this information.



This wording in the problem is far from to be perfect, is unprofessional and only confuses a reader.
