Brain weight B as a function of body weight W in fish has been modeled by the power functionB = 0.007W2⁄3,where B and W are measured in grams. A model for body weight as a function of body length L (measured in centimeters) isW = 0.12L2.53.If, over 10 million years, the average length of a certain species of fish evolved from 13 cm to 20 cm at a constant rate, how fast (in g/yr) was this species' brain growing when its average length was 19 cm?
