Assume that the balanced chemical reaction is as follows and that the reaction is independent of the reactant concentration (i.e., a constant reaction rate or zero-order reaction):

---> 2C2H5OH + 2CO2 from C6H12O6

To start, figure out how much ethanol has reacted in five hours. For consistency, I'll work in grams and mol.

#n(ethanol) = m/M=8000/46=173.91# mol

One glucose molecule will be converted to two ethanol molecules using the stoichiometric ratios of 1:2 (glucose:ethanol) in the chemical reaction; this indicates that the amount of glucose molecules used in five hours is half of the amount of ethanol molecules produced.

#"n(glucose)"=0.5*173.91=86.96# #mol#

The mass of glucose used in five hours is what we need next.

#"mass(glucose)"=n*M=86.96*180=15652.17# #g#

By dividing the mass of glucose that reacted by the reaction time, the rate of the reaction can be calculated.

#"rate of glucose consumption"=15652.17/5=3130.43# #"g"/"hr"#

Now that we know the mass of glucose that reacts and the rate for the 1000 kg, we can use algebra to solve for the number of hours. The mass reacted is equal to the rate multiplied by the number of hours.

#3130.43# #"g"/"hr"# #*x# #"hr"##=1000*10^3# #g#

We can rearrange and find the value of x with just one unknown.

#"x"=10^6/3130.43=319.44# #"hours"#

Cut by 24 to convert to days.

#319.44/24=13.31# #"days"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
