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:
x = 18.
