To calculate the unit rate for brake pads produced per hour, we would need the total number of brake pads produced over the 12-hour work day. Since you didn't provide the total number, I'll show you how to calculate the unit rate if you have that number.

  1. Let's denote the total number of brake pads produced in 12 hours as \( T \).
  2. The unit rate (brake pads produced per hour) can be calculated using the formula:

\[ \text{Unit Rate} = \frac{T}{\text{Total Hours}} = \frac{T}{12} \]

  1. Once you have the total number of brake pads, simply divide it by 12 to find the unit rate.

If you can provide the total number of brake pads produced, I can calculate the exact unit rate for you!
