SORRY THERE IS  A CORRECTION :       a bacterium divides  once in 20 minutes. if a bacterium takes 2hrs to fill up a cup, the time required to fill up a half cup is ?

Dear Student

Since the culture of bacteria fills the full cup in 2 hours(120 minutes) so obviously it would take 100 minutes to fill the half cup. Because in next 20 minutes all the bacteria in half cup will divide and fill the full cup.
