A roller conveyor moves tote pans at 200 ft/min between a load station and an unload sta- tion, a distance of 250 ft. The time to load parts into a tote pan at the load station is 0.05 min/part. Each tote pan holds 12 parts. In addition, it takes 0.15 min to load a tote pan onto the conveyor. One worker is assigned to loading the parts and then loading the tote pan onto the conveyor. Determine (a) the spacing between tote pan centers following in the conveyor system, and (b) the flow rate of parts on the conveyor system.
