## alainabbyboo22 3 years ago When movies are being created, the set designers often use miniature models before they create the actual movie set. The set designers for Jurassic Park 3, created a 6 inch high and 4 inch long model dinosaur that represented a 20 feet high dinosaur on the set. How long was the actual dinosaur, rounded to the nearest foot? A. 15 feet B. 13 feet C. 14 feet D. 12 feet
