A rubber-tired scraper with a heaped capacity of 60 cu yd has a cycle fixed time of 1.0 min (loading, dumping, and turning).
If the average speed of the scraper is 4.5 mph and it must travel a 1.5 mi round trip, calculate the anticipated production of the machine if it is hauling clay with a swell factor of 20%. Assume a machine efficiency of 46 min/hr.
