A model of a brontosaurus has a scale of ½ inch to 7 feet. From the tip of the nose to the end of the tail, the model is 6 inches long. What is the length of the brontosaurus?

jigglypuff314 (jigglypuff314):

12in = 1ft so 7ft = 7*12 = 84in 0.5in to 84in --> 1 to 168 ratio so multiply model length by 168
