one has a rate of \(\frac{1}{6}\) the other a rate of \(\frac{1}{4}\) the combined rate is the sum \(\frac{1}{6}+\frac{1}{4}=\frac{4+6}{6\times 4}\) you want to solve rate times time equals one job, i.e. \[\frac{4+6}{6\times 4}t=1\] so \[t=\frac{6\times 4}{4+6}\]
thanks
you can work it out step by step for each problem and get the same answer, but if you have to do more than one of these, say adam eats an apple if m minutes, eve eats an apple in n minutes, together they can eat the apple in \[\frac{m\times n}{m+n}\] minutes saves time , especially on a test or quiz
