It's very similar to the last problem x = time it takes Reggie to do the job alone (with no help) y = time it takes Rosalinda to do the job alone (with no help) z = time it takes to do the job if the two worked together All times (x,y,z) are in minutes In this case, x = 120 min y = 80 min z = unknown \[\Large \frac{1}{x} + \frac{1}{y} = \frac{1}{z}\] \[\Large \frac{1}{120} + \frac{1}{80} = \frac{1}{z}\] solve for z
