$6$ $6$ minutes.

Looking at your information:

You are looking for:

In knowing this, you can use ratios to solve.

Now, multiply the $30 L$ $"30 L"$ by $1 minute$ $"1 minute"$

$30 min \times 1 L = 30 min \cdot L$ $"30 min" xx "1 L" = "30 min" * "L"$

Now, divide the value by the $5 L$ $"5 L"$

$("30 min" \ * \ "L") / "5 L" = "6 minutes"$

A more simple method to solve this would be to see how many times the number $5$ fits into $30$ . So,

$30 / 5 = 6$

Therefore you need $6$ lots of $"5 L"$ to fill the bucket. This $6$ 'lots' is actually $6$ 'minutes'.
