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

1. MathMate

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

Its .076 in each beat .

3. Math Lover

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.

4. Math Is Life!!

0.076 Liters per beat!!!!!

5. WeirdQuestionsAnswered

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 beat
