Answer:
The answer is 5 minutes.
Step-by-step explanation:
You work as a dental hygienist, seeing patients for 6 hours each workday. Currently, you see 9 patients per workday.
Means for 1 patient you spend [tex]\frac{6}{9}=\frac{2}{3}[/tex] hours
Or [tex]\frac{2}{3}\times60=40 minutes[/tex] per patient.
When 8 patients are seen then per patient time spent is = [tex]\frac{6}{8}=\frac{3}{4}[/tex] hours
or [tex]\frac{3}{4}\times60=45 minutes[/tex] per patient.
Then in the second case you spend [tex]45-40=5[/tex] more minutes per patient.
Thus, the answer is 5 minutes.
