Reid can execute one security audit in 10 days. He works 4 times as fast as Greg. I f Reid and Greg were assigned to work Togeth
Bogdan [553]

Using the together rate, it is found that they would have finished the task in 8 days working together.

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

It is the sum of each separate rate.

In this problem, the rates are given as follows:

  • For Reid, it is of 1/10.
  • Greg works four times as slower as Reid, that is, one security audit takes 40 days, hence his rate is of 1/40.

Then, the together rate is given by:

\frac{1}{x} = \frac{1}{10} + \frac{1}{40}

\frac{1}{x} = \frac{4 + 1}{40}

5x = 40

x = 8

They would have finished the task in 8 days working together.
