Answer

Explanation:

Step1: Calculate the reduction in time

The reduction in time is (15%) of (30) minutes. Using the formula (a\times p) (where (a = 30) and (p=0.15)), we have (30\times0.15 = 4.5) minutes.

Step2: Calculate the new time

Subtract the reduction from the original time. Using the formula (a - b) (where (a = 30) and (b = 4.5)), we get (30- 4.5=25.5) minutes.

Answer:

(25.5)
