Answer:
11 hours
Step-by-step explanation:
Let's set up a proportion so we can cross-multiply. We know that her rate is constant, so
[tex]\frac{8 kg}{2 hr} = \frac{44 kg}{x hr}[/tex]
Keeping units in helps to make sure that you have your fractions right-side-up. Now cross-multiply:
8x = 44*2
8x = 88
x = 11 hours
