A worker$-$machine operation was found to involve $4\mathrm{.}7$ minutes of machine time per cycle in the course of $40$ cycles of stopwatch study. The worker$$s time averaged $3\mathrm{.}2$ minutes per cycle, and the worker was given a rating of $122$ percent $($machine rating is $100$ percent$).$ Midway through the study, the worker took a $10-$minute rest break. Assuming an allowance factor of $14$ percent of work time which is applied only to the worker element $($not the machine element$),$ determine the standard timA worker$-$machine operation was found to involve $4\mathrm{.}7$ minutes of machine time per cycle in the course of $40$ cycles of stopwatch study.
