The average human heart pumps about 60 milliliters of blood for each beat.

a. About how many liters of blood does your heart pump each day?

b. Do you think a reasonable degree of precision for this question would be to report the answer to the nearest 100 liters, 10 liters, 1 liter, or 1 milliliter? Explain your reasoning.

c. About how many gallons is this?

  1. assuming a heartbeat of 60/min, that's 86400 beats/day.

    86400*0.06 = ?

    since the volume is given in ml units, but we're dealing with thousands of beats, I'd say 1 liter would be appropriate for the answer.

    as for gallons, just look up the conversion factor and multiply.
