National Cranberry Cooperative

On a peak day when 18,000 barrels of cranberries arrive uniformly over an eleven hour period from 7:00 a.m. to 6:00 p.m., what is the maximum length of the truck queue? How long must the plant operate to process all the wet (water-harvested) berries? (Assume that 70 percent of the berries are wet, processing starts at 7:00 a.m., and the average truck holds 75 barrels.)
