It would take her 10.5 hours to drink the whole jug.
Step-by-step explanation:
Given,
Cups of water in jug = 7
Water drunk every hour = [tex]\frac{2}{3}[/tex] of cup
Let,
x be the number of hours.
According to given statement;
[tex]\frac{2}{3}x=7[/tex]
Multiplying both sides by [tex]\frac{3}{2}[/tex]
[tex]\frac{3}{2}*\frac{2}{3}x=7*\frac{3}{2}\\x=\frac{21}{2}\\x=10.5[/tex]
It would take her 10.5 hours to drink the whole jug.
