A supply package will be dropped from an airplane to an Arctic research station. The plane's altitude is 2000 ft, and its horizontal speed is 235 ft/s.
The angle of depression to the target is 14°.

a. To the nearest foot, what is the plane's horizontal distance from the target?
b. The plane needs to drop the supplies when it is a horizontal distance of 500 ft from the target. To the nearest second, how long should the pilot wait before dropping the supplies?
