When the machine is cold, as it is in the first hour of production, it takes 6 minutes to produce each molded flower pot. Thereafter, once it is warm, it takes only 5 minutes to produce each pot. How many additional pots are produced in the last hour of the day, compared to the first? Let's be accurate as possible.
In the first hour, it produces 60 / 6 = 10 pots. In the last hour, it produces 60 / 5 = 12 pots. 12 - 10 = 2 more pots are produced in the last hour.
The answer: 2.
