The table below shows the total number of brake pads produced by machines throughout a 12-hour work day.

Question

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

Answer 1

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.
