Final answer:
Ms. Woody checks 5 papers in 1 minute. In 68 minutes, Ms. Woody can check 340 papers.
Step-by-step explanation:
To determine the number of papers Ms. Woody can check in 1 minute, we divide the total number of papers she checks in 4 minutes (20 papers) by the time taken: 20 papers ÷ 4 minutes = 5 papers per minute. Hence, Ms. Woody checks 5 papers in 1 minute, establishing the rate at which she evaluates papers.
Next, to find out how many papers she can check in 68 minutes, we multiply the number of papers she checks in 1 minute (5 papers) by the total time: 5 papers/minute × 68 minutes = 340 papers. This multiplication represents the number of papers Ms. Woody can review within the given duration of 68 minutes, considering her consistent rate of checking 5 papers per minute.
Understanding the rate of work or activity per unit time helps in estimating the total work or output within a specific duration. In this scenario, determining Ms. Woody's rate of checking papers per minute enables us to calculate the total number of papers she can evaluate in a different time frame, such as 1 minute or 68 minutes. This method provides a straightforward approach to extrapolate her productivity across varying time intervals based on her established rate of checking papers per minute.
