The table below shows the total number of brake pads produced by machines throughout a 12-hour work day.
The table shows the number of brake pads produced in 3 hours is 48, 6 hours is 96, 9 hours is 144, and 12 hours is 192.
What is the unit rate for brake pads produced per hour?
A.
4 brake pads per hour
B.
3 brake pads per hour
C.
12 brake pads per hour
D.
16 brake pads per hour
To find the unit rate for brake pads produced per hour, we divide the total number of brake pads produced by the number of hours.
The table shows that in 12 hours, 192 brake pads are produced.
To find the unit rate per hour, we divide 192 by 12.
192 / 12 = 16
Therefore, the unit rate for brake pads produced per hour is 16 brake pads per hour.
The correct answer is D. 16 brake pads per hour.
