Explanation:

Step1: Recall percent increase formula

The formula for percent increase is $\text{Percent Increase} = \frac{\text{Amount of Increase}}{\text{Original Amount}} \times 100\%$.

Step2: Identify values

The original amount (Tuesday's practice time) is 25 minutes, and the amount of increase is 10 minutes (from part a).

Step3: Plug into formula

Substitute the values into the formula: $\frac{10}{25} \times 100\%$.

Step4: Calculate

First, $\frac{10}{25} = 0.4$. Then, $0.4 \times 100\% = 40\%$.

Answer:

40
