The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is constant. At a specific temperature the pressure is 102 kPa at sea level and 87.7 kPa at h = 1,000 m. (Round your answers to one decimal place.)

(a) What is the pressure at an altitude of 4000 m?
kPa
(b) What is the pressure at the top of a mountain that is 6463 m high?
kPa
