how did they get 2 hours for question 4c? Mark scheme doesn't explain it
So 3% + 1% + 6% (the cells in other stages of mitosis) = 10%. That means at any given time, on average, 10% of the cells are undergoing mitosis - hence, you can assume it takes them around 2 hours. 10% of 20 hours (for the whole cell cycle to complete) is 2 hours.
