Personnel and supply management will be of great concern throughout the expedition. Your managers consult with an operations research think tank to provide scheduling and operational efficiency, and coordination with departments regarding maximized routes for contingency and emergency management. (1) Once underway, operations on the ship will consist of two, primary shifts: a day shift, and a night shift that will only have half the number of personnel as the day shift. If there are 51 people working on the expedition, how many are in each shift? (2) The crew will require large supplies of toilet paper and movie DVDs. Toilet paper will be requisitioned at $0.35 per roll and DVDs at $6.50 per disc. One case of 50 toilet paper rolls has a volume of 4 cu.ft. and a case of 25 DVDs has a volume of 1.2 cu.ft. If the ship will be able to support a total volume of 464 cu.ft. for this cargo, and the quartermaster uses the total budget of $36625 for these supplies, how many DVDs and how many rolls of toilet paper will be ordered? (3) If the ST Anthony runs out of toilet paper, the nearest port for resupply is Sanya, on Hainan Island, approximately 180 nautical miles away. If the ship could get to Sanya from the search site in 12 hours while traveling with the current, and would take 15 hours to return to the search site against the current, what is the speed of the boat in still water and what is the speed of the current?
