Question 1140961: It takes an older computer twice as long to send out a company email as it does a newer computer. Working to gather it takes the two computers 15 minutes to send out the email. How long will it take the newer computer to send out the email on its own? Found 2 solutions by josgarithmetic, ikleyn:Answer by josgarithmetic(39617) (Show Source):
The new computer works twice as productive as the old one.
So, the two computers together work as productive as three slower computer.
Thus you can re-formulate the problem EQUIVALENTLY saying that three slower computers make the job in 15 minutes.
Hence, one single slower computer makes the job in 3*15 = 45 minutes.
The newer computer, working two times faster that the older one, will complete the job in 45/2 = 22.5 minutes.
ANSWER. The newer computer will complete the job in 22 minutes and 30 seconds.
