6 minutes.

Explanation:

Looking at your information:

  • "5 L = 1 minute"

You are looking for:

  • "30 L = ? minute/s"

In knowing this, you can use ratios to solve.

  • "5 L : 1 minute"
  • "30 L : ? minutes"

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

"30 min" xx "1 L" = "30 min" * "L"

Now, divide the value by the "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'.
