The accompanying table shows the time of useful consciousness at various altitudes in the situation where a pressurized airplane suddenly loses pressure. The change in pressure -0.274a , where T measures time in minutes and a is the drastically reduces available oxygen, and hypoxia sets in. The upper value of each time interval is roughly measured by T-10-2 altitude over 22,000 in thousands of feet (a = 0 corresponds to 22,000 ft). Complete parts a through c below.

According to this model, how long do the pilot and passengers have to deploy oxygen masks before they become incapacitated? T= S (Type an integer or decimal rounded to the nearest tenth as needed.)
