Using the together rate, it is found that it will take 18 hours for Erick to build the garden box himself.

<h3>What is the together rate?</h3>

The together rate is given by the sum of each separate rate.

In this problem, the rates are given as follows:

  • Eric's: 1/x.
  • Drew's: 2/x.
  • Together: 1/6.

Hence:

\frac{1}{x} + \frac{2}{x} = \frac{1}{6}

\frac{3}{x} = \frac{1}{6}

x = 18.

Hence, it will take 18 hours for Erick to build the garden box himself.

The definition of a statistical question is "a question that should have different answers". Therefore, this is a statistical question because the answers will be different from student to student.
