The kilopascal is a unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea level is about 104 kil
opascals. For every 1000-m increase in altitude, the pressure decreases about 11.9%. What is the approximate pressure at an altitude of 2000 m? The pressure at an altitude of 2000 m is about ___ kilopascals.
First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.
