Final answer:
To calculate the allowance, adjust the standard time of 1.76 minutes with the rating factor of 80% to get 2.20 minutes. Subtract this from the observed time of 2 minutes to find an allowance of -0.20 minutes, indicating a faster completion than the adjusted standard time.
Step-by-step explanation:
The question involves calculating the allowance given for an element based on its observed time, standard time, and rating factor. The observed time for the element is 2 minutes, and the standard time is given as 1.76 minutes. The rating factor is 80%, which is used to adjust the standard time to reflect normal performance.
First, we calculate the standard time adjusted for the rating factor:
Adjusted Standard Time = Standard Time / Rating Factor
Adjusted Standard Time = 1.76 / 0.80
Adjusted Standard Time = 2.20 minutes
The allowance is then calculated by subtracting the standard time from the observed time:
Allowance = Observed Time - Adjusted Standard Time
Allowance = 2 - 2.20
Allowance = -0.20 minutes
In this case, the negative allowance indicates that the task was completed faster than the adjusted standard time allows.
