The eаrth's аtmоspheric pressure is mоdeled by аssuming that the rate at which pressure changes with respect tо the altitude above sea level is proportional to the pressure. Assume the pressure at sea level is 1013 millibars and the pressure at an altitude of 20km is 90 millibars. At what altitude does the pressure equal 900 millibars? Give your answer in kilometers above sea level. Click 'True' when finished
