A drone traveling horizontally at 110 m/s over flat ground at an elevation of 4500 meters must drop an
emergency package on a target on the ground. The trajectory of the package is given by x = 110t ,
y = - 4.9t + 4500 ,t > 0 where the origin is the point on the ground directly beneath the drone at
the moment of release. How many horizontal meters before the target should the package be released in
order to hit the target? Round to the nearest meter.
