Step-by-step explanation:
Let v represent the volume of the 50% solution, in milliliters. Then 200-v will be the volume of 10% solution. The amount of alcohol in the mix will be ...
0.50v +0.10(200-v) = 0.48(200)
0.40v +20 = 96 . . . . . . simplify
0.40v = 76 . . . . . . . . . subtract 20
v = 190 . . . . . . . . . . . divide by 0.4
Kristina must mix ...
10 mL of 10% solution
190 mL of 50% solution

x=12*48=576
So it's 576 hours.
