Answer:
The number of bacteria at the end of 4th hour will be 480.
So if it takes 60 minutes to fill a cup, it must take 59 minutes to fill half a cup as in 1 minute half cup full of bacteria will double to fill the cup completely. Thus, it will take 59 minutes to fill half a cup with this bacteria.
