Answer:
12 minutes
Step-by-step explanation:
The water is at 36°C
The fridge reduces temperature at 3°C per minute
To attain a temperature of 0°C, we need the fridge to reduce the temperature by 36°C
Assume number of minutes = x
3x = 36
x = 36 ÷ 3
x = 12
Therefore the Fridge will need 12 minutes to freeze the water

Answer:
12 minutes
Step-by-step explanation:
As it steadily drops, 3 °C a minute, it goes from 36°C to 33°C after a minute, then from 33°C to 30°C after another minute. After counting down in that fashion, you will get to 0°C after 12 minutes.
