The rate of flow of blood is:

$\overline{){\mathbf{Q}}{\mathbf{=}}{\mathbf{A}}{\mathbf{v}}}$, where Q is the flow rate given in L/s, v is the speed of blood, and A is the cross-sectional area of the aorta.

We know that A = πr^{2}

Suppose blood is pumped from the heart at a rate of 4.9 L/min into the aorta of radius 0.85 cm. Determine the speed of blood through the aorta, in centimeters per second.
