his disguise as Mad Dog Moody. How many days would 5 gallons of potion last him?
128 fl. oz. = 1 gallon

Answer 1

By the use of proportion, it would last him for 6.67 days.

How many days would 5 gallons of potion last him?

From the question, we already had the information that the evil Barty Crouch Jr. had to drink at least 4 fl. oz. of Polyjuice Potion every hour in order to maintain his disguise as Mad Dog Moody.

Now;

If 128 fl. oz. = 1 gallon

   x  = 5 gallons

x = 640 fl. oz

If he takes  4 fl. oz. in 1 hour

He would take640 fl. oz  in x hours

x =  640 fl. oz * 1 hour/4 fl. oz

x = 160 hours

1 day is made up of 24 hours

x days is made up of 160 hours

x = 6.67 days
