Beyond the Answer

To find out how much water is lost per hour through the cracks, we can do the following calculations: Each of the 4 cracks releases liter per hour, so the total loss from all cracks is liters per hour.
Now, to determine how much the emergency pump needs to run, we need its rate of filling. If it fills at a certain rate, let’s say liters per minute, you want to convert that to liters per hour. Since there are 60 minutes in an hour, the pump fills liters per hour.
To replace the water lost, you set up the equation: . Solving for gives you liters per minute.
For the pump to replace the 2 liters lost in one hour, it must run for 2 minutes. If the pump runs for 2 minutes at this rate, it will replace the lost water, keeping your aquarium full and happy!
