order:dextrose 5% 0.9 NaCl 1000 ml over 6 hours. Drop factor is 60 gtt/ml. How many ml/hr will the infusion need to be set? Round to the nearest whole number.

I was thinking ok should it 1000 ml x 60 gtts

6hrsx 60 mins=. 167 rounded, but here is my problem they did not ask drops per min, it says ml/hr i am confused.
