Question

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, Write a formula for the circulation time, T, in terms of the body mass Use k as the constant of proportionality. T = If an elephant of body mass 5230 kilograms has a circulation time of 148 seconds, find the constant of proportionality, Round your answer to one decimal place. k = 17.4 What is the circulation time of a human with body mass 90 kilograms? Round your answer to the nearest integer.

Explanation / Answer

T = K B^1/4 => 148 = K [5230]^1/4 =>K = 17.4 T = 17.4 [90]^1/4 = 53.59 sec
