1point) air pressure decreases at a rate of 1.75 pa (pascals) per kilometer in the eastward direction. in addition, the air pressure is decreasing at a constant rate with respect to time everywhere. a ship sailing eastward at 8 km/hour past an island takes barometer readings and records a pressure drop of 30 pa in 2 hours. estimate the time rate of change of air pressure on the island. (pascal is a unit of air pressure 1pa=1n/m2=1kg/m∗s2) time rate of change of air pressure = pa/hr
