My answer was 28 seconds, but i am now getting told the answer is 30 seconds. How can this be? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! How many cuts do you have to make to get 5 pieces ? 4 cuts at 5 seconds each=20 seconds
How many cuts do you need to make to get 7 pieces. 6 cuts at 5 seconds each = 30 seconds
