To find the height of a building, Oscar stuck the end of a 4 ½-foot stick 6 inches straight into the ground. He measured the shadow of the stick and found it was 1 foot long. Oscar then measured the building's shadow and found it was 16 feet long.
How many feet from the building was the stick?
The stick's distance from the building has nothing to do with the matter. Even if it was twice as far from the building, all of the given facts would stay the same. Without more information, there is no way to figure out how far the stick is from the building.
