Question

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 Click the icon to view the time of useful consciousness table a A jet flying at 42 000 ft a 20 suddenly loses pressure when the seal on a window fails 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
