Question

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

Answer 1

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

What is the together rate?

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.
