In the human body, blood travels faster in the largest blood vessel, the aorta than in any other blood vessel. Given an average speed of 30 cm/s, how long would it take the blood to travel 5 cm?

  • Physics -

    D=R*T, solve for T

    D/R=T= (5cm/30cm/s)

  • Physics -

    t=s/v=5cm.s/30cm=0.16s
