Question

A lab technician must screen 175 slides under the microscope each week. If she works 7 hours a day, 5 days a week, how many slides,on average, must she screen in one hour

Answer 1

Answer:

The lab technician must screen 5 slides per hour

Step-by-step explanation:

If the lab technician works 5 days a week, and 7 hours per day, then she works 5*7 = 35 hours a week.

Given she must screen 175 slides each week, we can calculate on average, the number of slides per hour needed to complete the work.

The average is calculated as:

$\displaystyle average=\frac{\text{total slides}}{\text{total hours}}$

$\displaystyle average=\frac{175}{35}=5\ slides/hour$

The lab technician must screen 5 slides per hour
