Three submittals were returned in 6, 9, and 12 days. What was the average turnaround?
Correct Answer
A) 9 days
Average turnaround is (6 + 9 + 12) / 3 = 9 days.
Why This Is the Correct Answer
Average turnaround is (6 + 9 + 12) / 3 = 9 days.
Why the Other Options Are Wrong
Option B: 6 days
submittal turnaround average, choice a: the number 6 days comes from 6 but stops before the calculation reaches 9 days.
Option C: 10 days
submittal turnaround average, choice c: 10 days backs into 3.33 when divided by 3; the accepted setup gives 3 on that same base.
Option D: 27 days
submittal turnaround average, choice d: 6, + 9, + 12 gives 27 days. That calculation adds three listed values.
Memory Technique
Remember submittal turnaround average as "base, adjustment, final unit"; the last unit should read 9 days.
Reference Hint
Open Construction Jobsite Management, 5th Ed. (2024); use by topic index - documentation / submittals / RFIs / closeout to confirm that Average turnaround is (6 + 9 + 12) / 3 = 9 days.
