An airplane flies horizontally above the flat surface of a desert at an altitude of 5 km and a speed of 915 km/h. If the airplane is to drop a care package that issupposed to hit a target on the ground, where should the plane be with respect to the target when the package is released? (Enter the horizontal distance between theplane and the target.) If the target covers a circular area with a diameter of 45 m, what is the "window of opportunity" (or margin of error allowed) for the release time?
