Answer
During one beat of the heart, the blood moves approximately 8 cm
Work Step by Step
The area between the velocity versus time graph and the x-axis is equal to the displacement.
From t = 0.1 s to 0.3 s, the area under the velocity versus time graph is $\frac{1}{2}(0.8 ~m/s)(0.2 ~s)$ which is 0.08 m
Therefore, during one beat of the heart, the blood moves approximately 8 cm
