The formula to calculate the Percent Decrease Over Time (PDT) is:
\[ \text{PDT} = \frac{\text{PD}}{\text{T}} \]
Where:
Time improvement is a measure of the reduction in time taken to complete a task or activity compared to a previous attempt. It is often expressed as a percentage to indicate the efficiency gain or performance increase. This metric is commonly used in sports, manufacturing, project management, and any scenario where time efficiency is crucial.
Let's assume the following:
Step 1: Calculate the Percent Decrease Over Time:
\[ \text{PDT} = \frac{20}{5} = 4\%/\text{unit time} \]
Therefore, the Percent Decrease Over Time is 4% per unit time.
