A project requires transporting 13,000 cy of sand using (12) - cy dump trucks. A front-end loaded will load trucks at a rate pf 95 cy / hr. The trucks will transport the sand (7) miles at an average haul speed of 30 mi / hr, return speed of 40 mi / hr, and dump time of (3) minutes. Assume a (45) min effective hour for all equipment. (a) Calculate the number of trucks required to balance the production rate of the loader and (b) estimate the time to transport the sand based on the calculated number of trucks.
