It is given that the doubling time of the given bacteria is 3 minutes. It means that the generation time of given bacterial cells is 120 seconds. If it takes 60 minutes to fill a cup, it will take 59 minutes to fill half the cup and 58 minutes to fill 1/4 cup.
At 58th minute, the cup will be one fourth-filled and in the 59thminute, the bacterial cell will double up and cup will be half filled. At 60th minute, the bacterial cell will double up and cup will be fully filled.
