We are given:

Ivanna's fish tank has 18 liters of water in it

She plans to add 5 liters per minute till the tank has 48 liters

We will proceed to solve for the possible number of minutes as shown below:

[tex]\begin{gathered} 18+5t\ge48 \\ \text{Subtract ''18'' from both sides, we have:} \\ 5t\ge48-18 \\ 5t\ge30 \\ \text{Divide both sides by ''5'', we have}\colon \\ t\ge\frac{30}{5} \\ t\ge6 \\ \end{gathered}[/tex]

Therefore, it would take at least 6 minutes for the tank to have at least 48 liters of water in it
