One of the fun facts about rates is that they help us understand how things change over time! For the checkout clerk, knowing how fast they’re processing transactions can lead to better customer service. So, the rate of \( \frac{6 \text{ transactions}}{20 \text{ minutes}} \) shows that they're serving customers at a steady pace, approximately 0.3 transactions per minute. To optimize performance, the clerk could work on improving their speed to handle more transactions in the same time frame. For instance, if they could reduce the time per transaction to about 3 minutes and 20 seconds, they’d notch up productivity. Juggling efficiency while maintaining customer satisfaction is key – let's keep those lines moving smoothly!
