The continuous timing method in direct time study was used to obtain the element timesfor a worker-machine task as indicated in the table below. Element c is a machine-controlledelement and the time is constant. Elements a, b, d, e, and f are operator-controlled andexternal to the machine cycle, and they were performance rated at 80%. If the machineallowance is 25%, and the worker PFD allowance is 15%, determine (a) the normal time,(b) the standard time for the cycle, and (c) the worker’s efficiency if the worker completes360 work units working 7.2 hr on an 8-hour shift. **Table: Observed Time for Various Elements**This table lists the observed time (in minutes) for different elements labeled from 'a' to 'f'. Each element is associated with a specific observed time value.| Element | \( a \) | \( b \) | \( c \) | \( d \) | \( e \) | \( f \) ||---------|---------|---------|---------|---------|---------|---------|| Observed time (min) | 0.18 | 0.30 | 0.88 | 1.12 | 1.55 | 1.80 |- **Element 'a'**: Observed time is 0.18 minutes.- **Element 'b'**: Observed time is 0.30 minutes.- **Element 'c'**: Observed time is 0.88 minutes.- **Element 'd'**: Observed time is 1.12 minutes.- **Element 'e'**: Observed time is 1.55 minutes.- **Element 'f'**: Observed time is 1.80 minutes.This table can be utilized for comparative analysis of times associated with each element.

Question

The continuous timing method in direct time study was used to obtain the element times
for a worker-machine task as indicated in the table below. Element c is a machine-controlled
element and the time is constant. Elements a, b, d, e, and f are operator-controlled and
external to the machine cycle, and they were performance rated at 80%. If the machine
allowance is 25%, and the worker PFD allowance is 15%, determine (a) the normal time,
(b) the standard time for the cycle, and (c) the worker’s efficiency if the worker completes
360 work units working 7.2 hr on an 8-hour shift.
