If one individual can complete a job in H1* hours alone, and another individual can complete the same job in H2* hours alone, then the amount of hours it would take them to complete the job working together, T, is given by the equation:

T/H1* + T/H2* = 1


QCcant be D if...

there are no variables


If group of size N1* completes a job in H1* hours, and another group of size N2* completes the same job in H2* hours, then

N1* x H1* = N2* x H2*
