If the machine delivers 2 liters of blood every 20 seconds, how
many liters does it deliver per minute?
Liters per minute = (60 seconds
per minute / 20 seconds) x 2 liters per 20 seconds
Liters per minute =
3 x 2
Liters per minute = 6
1 hour = 60 minutes
Total
= 60 minutes x 6 liters per minute
Total = 360 liters
1.5
hours:
Total = (1.5 hours x 60 minutes per hour) x 6 liters per minute
Total
= 90 minutes x 6 liters per minute
Total = 540 liters
2.5
hours:
Total = (2.5 hours x 60 minutes per hour) x 6 liters per minute
Total
= 150 minutes x 6 liters per minute
Total = 900 liters
3
hours:
Total = (3 hours x 60 minutes per hour) x 6 liters per minute
Total
= 180 minutes x 6 liters per minute
Total = 1,080 liters
4
hours:
Total = (4 hours x 60 minutes per hour) x 6 liters per minute
Total
= 240 minutes x 6 liters per minute
Total = 1,440 liters
5
hours:
Total = (5 hours x 60 minutes per hour) x 6 liters per minute
Total
= 300 minutes x 6 liters per minute
Total = 1,800 liters
5.5
hours:
Total = (5.5 hours x 60 minutes per hour) x 6 liters per minute
Total
= 330 minutes x 6 liters per minute
Total = 1,980 liters
6
hours:
Total = (6 hours x 60 minutes per hour) x 6 liters per minute
Total
= 360 minutes x 6 liters per minute
Total = 2,160 liters
