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

2.8 million a year divided by 365 days in a year = 7671.233 liters a day.
7671.233 liters a day divided by 24 hours in a day=319.63 liters an hour
319.63 divided by 1440 minutes in a day=5.372 liters a minute
5.372 divided by 70 beats per minute=0.076 liters per beatposted by WeirdQuestionsAnswered
