To find out how many products are selected every hour for inspection on a line where a product is selected every 12 minutes, divide 60 minutes by 12 minutes per product, resulting in 5 products selected every hour.
To calculate the number of products selected per hour, we first establish the rate of product selection per minute. Given that a product is selected every 12 minutes, we divide the total minutes in an hour (60) by this selection interval: 60 / 12 = 5.
This quotient represents the number of selections within one hour. Since only one product is chosen during each selection interval, we multiply the result by 1, yielding a final count of 5 products selected every hour.
This method allows us to scale up the selection rate from minutes to hours, providing a clear understanding of the hourly product selection rate. This calculation is particularly useful for processes where events occur at regular intervals, allowing for efficient scaling of rates to larger timeframes. In this specific scenario, it demonstrates that the selection process results in 5 products being chosen each hour.
Therefore, the question may be:
You work on a line where a finished product is selected every 12 minutes for inspection. At that rate, how many products are selected every hour?
