Vehicles arrive at a single toll booth beginning at 8:00AM. They arrive and depart according to a uniform distribution. However, the toll booth does not open until 8:10AM. The average arrival rate is 8 veh/min. The average departure rate is 10 veh/min. When does the initial queue clear, and what is the total delay, the average delay per vehicle, and the longest queue length (in vehicles)

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
