Question

Bacterial cell divides every one minute. It takes 28 minutes a cup to be one fourth full . How much time will it take to fill the cup ?​

Answer 1

Answer:

in 59 minutes the cup will fill full.

Explanation:

It is given that the doubling time of the given bacteria is 1 minute. It means the generation time of given bacterial cells is 60 seconds. If it takes 60 minutes to fill a cup, it will take 59 minutes to fill half the cup.  

At 59th minute, the cup will be half-filled and in the 60th minute, the bacterial cell will double up and cup will be full filled.
