1000 mL has been infused in 8 hours at 150 ml/hr. After 3 hours, how many have been infused?
1000/8 = 125 ml
125 x 3
=375ml?
Therefore after 3 hours 375ml has been infused
Is this correct?
since the rate is 125ml/hr, why does it say 150 ml/hr?
Anyway, your calculations look good.
but watch the units.
1000ml/8hr = 125 ml/hr, not 125ml
125ml/hr * 3hr = 375ml
Thank you!
Almost correct! Let's break it down step by step.
First, you correctly calculated that the total volume is 1000 mL and the infusion rate is 150 mL/hr.
To find out how much has been infused after 3 hours, you calculated the rate (125 mL/hr) by dividing the total volume (1000 mL) by the total time (8 hours), which gave you 125 mL/hr.
Then, you multiplied the rate (125 mL/hr) by the time (3 hours) to find out how much has been infused, which gave you 375 mL.
So, after 3 hours, 375 mL has been infused. Great job!
