Answer:

#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'.
