At the rate of L liters per S seconds, how many kiloliters (1000 liters = 1 kiloliter) of blood does the heart pump in X hours?
A. 3,600LX/(1,000S)
B. 1,000LX/(3,600S)
C. 3,600,000XS/L
D. 3,600,000LS/X
E. 3,600,000LXS/
Let’s convert the rate to kiloliters per second.
L liters = L/1000 kiloleters. So, our new rate is:
(L/1000)/S = L/(1000S)
Now we need to determine how much blood is pumped in X hours, or 3600X seconds.
L/(1000S) * 3600X = 3600XL/(1000S)
Answer: A
