An aircraft has a glide ratio of 12 to 1. (Glide ratio means that the plane drops 1 m in each 12 m it travels horizontally.) A building 47 m high lies directly in the glide path to the runway. If the aircraft clears the building by 12 m, how far from the building does the aircraft touch down on the runway? The aircraft touches down the building at a distance of × 102 m on the runway.
