A. 3,600LX/(1,000S)
B. 1,000LX/(3,600S)
C. 3,600,000XS/L
D. 3,600,000LS/X
E. 3,600,000LXS/ L litre = S Sec L/S litre = 1 Sec L/S * 60 Litre = 1 min L/S * 60 * 60 Litres = 1 hour 3600L/1000S Kilo Litres = 1 hour 3600LX/1000S Kilo Litres = X hours A

1 hr= 60 min, 1 min=60 sec Therefore 1 hr=60*60=3600 sec
Rate is L liters per S seconds therefore Rate in liters per hour is 3600 L/hr And finally Rate in kilo liters per hour is 3600 KL/1000 hr
Therefore in x hours, 3600xL/1000s blood will be pumped. hence Option A.
Kudos if it helps.

C. 3,600,000XS/L
D. 3,600,000LS/X
E. 3,600,000LXS/ L litre = S seconds In Xhrs there would 3600*X seconds So volume pumped = 3600*X*L /S litres In kilolitres 3,600LX/(1,000S) Ans:A

L litres per S sec > L/S = 1 sec 1 hr = 3600sec 1 kilolitres = 1000L
In S Sec > L litres blood pumped In X hours(3600S) > 3600LX blood pumped In kilolitres > 3600LX/1000S
Option A

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

E. 3,600,000LXS/ Bunuel how would you solve this question? Please explain in simplified form. This one is confusing. 1000 liters = 1 kiloliter, thus L liters = L/1,000 kiloliter The rate of L liters per S seconds = \(Rate = \frac{Job \ done}{Time} = \frac{(\frac{L}{1,000})}{S}= \frac{L}{1,000S}\) liters per second. Since, there are 3,600 seconds in one hour, then the rate in liters per hour would be \(\frac{3,600L}{1,000S}\) liters per hour. \(Job \ done = Rate*Time = \frac{3,600L}{1,000S}*X = \frac{3,600LX}{1,000S}\). Answer: A.
