A fully trained operator performed a three-element job for seven cycles. Element times, in hundredths of a minute, are given in the table below. Each of the three elements is pace-rated separately. An overall PR&D allowance factor of 15 percent is applied.
a. Compute the average elemental times.
b. If the pace ratings for the three elements are A-112, B-90, and C-100, compute the normal time for each element and the total normalized time.
c. Compute the standard time.
d. How many cycles would a trained operator be expected to complete in one hour?
