First Storm :_ mL/hr
Second Strorm:_mL/hr Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! First storm x ml/hr
second storm 50-x ml/hr
..
first storm 25 hours
second storm 40 hours
..
total was 1775 ml
..
25x+(50-x)*40=1775
25x+2000-40x=1775
-15x=-225
x=15 ml/hr first storm
y=35ml/hr second storm
..
15 ml/hr first storm
35ml/hr second storm
