worker-machine operation was found to involve 4.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. he worker's time averaged 2.8 minutes per cycle, and the worker was given a rating of 118 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 18 percent of work time which is pplied only to the worker element (not the machine element), determine the standard time for this job. (Do not round intermediate :alculations. Round your final answer to 2 decimal places.)
