Answer:
she must screen at least 5 and hour
Step-by-step explanation:
175/5=35 a day
35/7=5 and hour
The number of slides, on average, the lab technician can screen in one hour is 5 slides.
Given,
A lab technician must screen 175 slides under the microscope each week.
She works 7 hours a day.
She works 5 days a week.
We must find how many slides she screens in one hour.
We have,
A lab technician must screen 175 slides under the microscope each week.
One week = 175 slides.
She works 5 days a week.
One week = 5 days.
She works 7 hours a day.
1 day = 7 hours.
Multiply 5 on both sides.
5 x 1 day = 5 x 7 hours
5 days = 35 hours.
So,
One week = 5 days
One week = 35 hours
One week = 175 slides
So,
35 hours = 175 slides
Dividing both sides by 35.
35 / 35 hours = 175 / 35 slides
1 hour = 5 slides.
Thus in one hour, the lab technician can screen 5 slides.
