The noted Medieval scholar, Professor Otto Rosseforp, is the author of Dragon Physics, a scholarly work outlining his theory of dragon flight. In his paper, the professor claims that mature dragons were able to fly
because of the presence of gasses in their intestinal tracts. The professor explains that when a dragon ate
certain foreign "foods”, methane and ammonia gasses were produced in the digestive process. This gas
collected in the lower intestinal cavity and provided the lift for the dragon flight. When the dragon's stomach
became too upset or it wished to land, the methane gas was ignited by the sparking of metals (old swords
stuck in its teeth), and the gasses were burned off. This was the cause of the reports of "fire-breathing
dragons." After years of studying reports of large and small dragons in medieval manuscripts, the professor
has come to the conclusion that a small dragon of 6 m in length had the stomach capacity to eat 440 kg of
"food." 440 kg was equivalent to nine fair damsels or four large Knights (in armor). The 440 kg of "food" was
capable of giving a 6 m dragon a flight distance of 50 km. If the stomach capacity of a dragon was proportional
to the cube of its length, then what was the food capacity of a dragon of length 18m? If the distance a dragon
was capable of traveling on one meal was directly proportional to its stomach capacity, then how far could a
dragon of 18 m length travel on a full dinner?
