Karen's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Karen could add water?

Karen has to at least spend 11 minutes.

Step-by-step explanation:

This is because 57 - 13 = 44. 44 divided by 4 = 11. This means that in 11 minutes Karen will have a 57 liter tank. But she could keep going, but the least number of minutes would be 11 minutes, to get to 57 liters.

I hope this helps! Please mark me Brainliest if it did! Thank you and have a nice day!

10 minutes

Step-by-step explanation:

Target = 57 liters

Already has 13 liters

Addition of 4 liters per minute.

The remaining liters to be filled = 57 liters - 13 liters = 44 liters

If 4 liters is to be added every minutes to fill up 44 liters

∴ 44 / 4 = 10 minutes
