How do I explain this problem?
A trucker handed in a ticket at a toll booth showing that in 2 h he had covered 159 mi on a toll road with speed limit 65 mph. The trucked was cited for speeding, why?
I know it is mean value theorem, but how?
His average speed was 159/2 = 79mph. There is no way he can have an average greater than the max speed limit w/o speeding.
