Answer 2

Let x represent time it would take to do the job if they all worked together. Question states***Per hour the Equalizer 1/6 + 1/2 + 1/3 = 1/x. Solving for x x + 3x + 2x = 6

Multiplying by 6x to get 1

6x = 6

x = 1hr, If they work together....

We can check the answer: ***

1/6 + 3/6 + 2/6 = 1
