To find the unit rate, we need to divide the number of brake pads produced by the number of hours worked.
For 3 hours: 48 brake pads / 3 hours = 16 brake pads per hour
For 6 hours: 96 brake pads / 6 hours = 16 brake pads per hour
For 9 hours: 144 brake pads / 9 hours = 16 brake pads per hour
For 12 hours: 192 brake pads / 12 hours = 16 brake pads per hour
The unit rate for brake pads produced per hour is 16 brake pads per hour. Therefore, the correct answer is D. 16 brake pads per hour.
The table below shows the total number of brake pads produced by machines throughout a 12-hour work day.
Hours Worked 3, 6, 9, 12
