A plane needs to drop supplies off to victims of natural disasters around the world. The first stop is for flood victims but they must drop the box so it lands perfectly on a target. If they are flying at 153 m/s and are 126 m above the ground, what distance before the target should they drop the package?

h = 0.5g*t^2.
126 = 4.9t^2, t = 5.07 s. to reach gnd.

d = Vx*t = 153 * 5.07 = 775.85 m.
