In a horror movie featuring a giant beetle, the beetle appeared to be 50 feet long. However, a model was used for the beetle that was really only 20 inches long. A 30-inch tall model building was also used in the movie. How tall did the building seem in the movie?

20 is to 50 as 30 is to what number... lets write this like fractions: 20 30 -- = -- 50 x What do you get from here?
