The leak in Jerry's roof drips 3 drops a minute into the pot he put under it. Each drop is 20 ml, and the pot holds 3 liters. How long will it take the pot to be full?
Reason slowly and give your answer.
50
First find the pot's volume in ml: 3 liters * 1000 ml / liter = 3000 ml.

Then find the number of ml that enter the pot per minute: 3 drops / minute * 20 ml / drop = 60 ml / minute.

Then divide the volume of the pot by the volume that enters it every minute: 3000 ml / 60 ml / minute = 50 minutes.

The answer: 50
