Question

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?

Answer 1

Answer:

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.

Answer 2

Answer:

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
