Calculate the time needed for a drip to deliver 65 drops/minute, given a 1.6L solution has a drip rate of 15 drops/mL
+37170 OK.....but I think you messed up your question....
I will assume 65 drops/ min and 15 drops / ml how much time to 'drip out ' 1.6 liter
65 d/min / 15 d/ ml = 4.3333 ml/min
1600 ml /4.3333 ml/min = 369.23 min = 6 hrs 9.23 min

I have my own pet method for doing rates like these :))
\(you\;\;have\\~\\ \frac{65drops}{1minute},\qquad 1600ml, \qquad \frac{15drops}{1ml} \qquad want \;\; minutes?\\~\\ \frac{1minute}{65drops}\times \frac{15drops}{1ml}\times \frac{1600ml}{1}\\~\\ \mbox{drops cancel and ml cancel}\\~\\ =\frac{1minute\times 15\times 1600}{65\times 1 \times 1}\\~\\ =\frac{ 15\times 1600\;}{65}\;minutes\\~\\ \approx369\;minutes\\~\\ \approx\;6hours\;\; and \;\;9\;minutes\\~\\\)
Any questions anyone?
