Johanna, Elizabeth, and Dan are preparing a chemical solution for a research project. When

Bond [772]

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.

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

It is the sum of each separate rate.

In this problem, the rates are given by:

Johanna's: 1/6.

Elizabeth's: 1/6.

Dan's: 1/4.

Hence the together rate is given by:

$\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}$

$\frac{1}{x} = \frac{1}{3} + \frac{1}{4}$

$\frac{1}{x} = \frac{4 + 3}{12}$

7x = 12

x = 12/7

x = 1.71.

They would prepare the solution in 1.71 minutes working together.
