To find the unit rate in kits per minute, the time must first be converted from hours to minutes. Since there are 6060 minutes in one hour, 2.52.5 hours is equivalent to 150150 minutes (2.5×60=1502.5 \times 60 = 150). Next, divide the total number of ration kits by the total number of minutes: 4,500÷150=304,500 \div 150 = 30. The system processes 3030 ration kits per minute.
