Question

Refer to the graph in Figure I.8 to answer the following questions.
a. If you were to climb to the top of Mount Everest, how many
breaths of air would you have to take at that altitude to equal one
breath at sea level?
b. If you were flying in a commercial jet at an altitude of 12 kilometers
(about 39,000 feet), about what percentage of the atmosphere
would be below the plane?
