A heart pumps about 5 quarts of blood through its chambers every 60 seconds. A swimming pool (20 ft. by 60 ft.) will hold about 65,000 gallons of water. This represents the amount of blood pumped by your heart in approximately how many weeks? (Remember you can have a partial week)

Answer 1

amount=volume/rate=65,000/(1.2/60)= 65,000*60/1.2 seconds

convert that to weeks.

Answer 2

5qts * 1gal./4qts * 1/60s = 0.0833 gal./s.

T = 65,000gal. * 1s/0.0833gal * 1h/3600s = 216.67 Hours.

T = 216.67h * 1day/24h * 1wk/7day = Weeks.
