Question 729529: Working together, it takes two computers 15 minutes to send out a company’s email. If it takes the slower computer 60 minutes to do the job on its own, how long will it take the faster computer to do the job on its own? Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! Working together, it takes two computers 15 minutes to send out a company’s email. If it takes the slower computer 60 minutes to do the job on its own, how long will it take the faster computer to do the job on its own?
.
Let x = time (minutes) it takes faster computer to do job alone
then
15(1/x + 1/60) = 1
multiplying both sides by 60x:
15(60 + x) = 60x
900 + 15x = 60x
900 = 45x
20 minutes = x
