The formula to calculate the percentage improvement in time is:
\[ I = \left(\frac{IT - FT}{IT}\right) \times 100 \]
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 improvement percentage:
\[ I = \left(\frac{120 - 90}{120}\right) \times 100 = 25\% \]
Therefore, the time improvement is 25%.
