The circulation time of a mammal (that is, the average time it takes for all the blood in the body to circulate once and return to the heart) is proportional to the fourth root of the body mass of the mammal. Let the circulation time be YY and the body mass be xx.(a) If an elephant of body mass 5800 kilograms has a circulation time of 122 seconds, find the constant of proportionality.(b) Write a formula for the circulation time in terms of body mass. Y(x)=Y(x)=(c) Assume that the constant of proportionality is the same for all mammals. What is the circulation time of a human with body mass 62 kilograms?
