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?

hours worked 3 6 9 12
brake pads produced 48 96 144 192

To find the unit rate for brake pads produced per hour, divide the total 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.
