Question

Quizplus · Accepted Answer

At noon, $\frac{2}{5}$ of the 1-liter (1000 ml) bag has been infused, which means $1000 \times \frac{2}{5} = 400$ ml has been infused. The remaining volume is $1000 - 400 = 600$ ml. At an infusion rate of 120 ml/h, it will take $600 \div 120 = 5$ hours to complete the infusion. Therefore, if it's noon now, the infusion will be complete at 5 P.M.
