An Adult male's heart pumps about 2.8 million liters of blood a year. If his heart beats 70 times a minute, how much blood does his heart pump with each beat? Show work

  • Math -

    Volume per beat
    = total volume / number of beats
    = 2800000 litres / (365*24*60 minutes * 70 beats per minute)
    = 0.076 l. / beat

  • Math -

    Its .076 in each beat .

  • Math -

    2.8million liters in a yr.
    is 7671.233 liters a day
    which is 319.63 per hr.
    which is 5.327 liters per min.
    which is .076 liters per beat!
    So , the answer is .076 liters per beat.

  • Math -

    0.076 Liters per beat!!!!!
