Air pressure decreases at a rate of 2.5 pascals per kilometer in the eastward direction. In addition, the air pressure is increasing at a constant rate with respect to time everywhere. A ship sailing eastward at 10 km/hour past an island takes barometer readings and records a pressure drop of 30 pascals in 2 hours. Estimate the time rate of change of air pressure on the island. (A pascal is a unit of air pressure.)
What is the time rate of change of air pressure?

In 2 hrs, the ship has traveled a distance 2(10)=20 km.
The time rate change of the air pressure on the island=
-30/2=-1.5 p/h.
