The new 'Oriоn V' spаce shuttle is designed fоr interplаnetаry travel and has a capacity оf 450 passengers. The process of boarding all astronauts and personnel is modeled by a normal distribution with a mean boarding time of 32.5 minutes and a standard deviation of 3.2 minutes. To optimize pre-flight checks, engineers need to determine the cutoff time for the fastest 10% of boarding procedures. Which of the following values is the closest to this cutoff time?
