The Truth About Work Rates: GRE / GMAT (with official example!)

No formulas, no tables, no complex methods. Here is my way to tackle work rate questions on the GRE and GMAT. We will test this method on an official work rate question.
I am here to bring you good news. If you bear in mind 2 core truths, work rate isn’t that bad! In fact, it can be very fun!
First truth: When combining work rates you can’t add the ‘time’ we take, but you can add the ‘rate’ we go at.
Second Truth: Rates and Times are reciprocals of each other
This is a Numeric Entry question.
1. Working alone at its constant rate, machine A produces k liters of a chemical in 10 minutes. Working alone at its constant rate, machine B produces k liters of the chemical in 15 minutes. How many minutes does it take machines A and B, working simultaneously at their respective constant rates, to produce k liters of the chemical?
______ minutes
Extreme Question
Working alone at her constant rate, Danya takes 2 hours to paint 1/2 a wall. Working alone at her constant rate, Aurelie takes 3 hours to paint 2 walls of the same size. If Danya starts painting a wall on her own for 3 hours, and is then joined by Aurelie, for how many hours will Aurelie and Danya now have to work together to finish 3 walls? Write your answer as a fraction.
GRE work rates and GMAT work rates will be tested in a very similar way, so I have lumped them together.

    Hi, Thank you for your videos. For the first question, can we convert the 10 mins as 10/60(1/6) then the 15 mins as 15/60(1/4) find the reciprocals and add the which should give (6+4 =10) then to find the time find the reciprocal of 10 and multiply by 60mins (1/10*60 =6). Should this also work ? thank you
