Answer 1

Answer:

a. 59 min

Explanation:

After one hour, the cup is full. The last time the bacteria divided, the number of cells must have been half of what it is now, because bacterial cells always divide to double their number. They took one minute to reach the number of cells they have now. So, the last time they divided was one minute ago. So, one minute ago, i.e. at 59 min, the number of cells of bacteria was half of what it is now, i.e. half the cup.
