Question

It takes an older computer twice as long to send out a company's email as it does a newer computer. working together, it takes the two computers 5 minutes to send out the email. how long will it take the newer computer to send out the email on its own?

Answer 1

Let's assume that it takes the newer computer "x" minutes to send out the email on its own. According to the information given, the older computer takes twice as long, so it takes "2x" minutes for the older computer to send out the email on its own.

When the two computers work together, their combined efficiency allows them to send out the email in 5 minutes.

To solve the problem, we can set up the equation:

1/x + 1/(2x) = 1/5

Multiplying all terms by 10x to eliminate the denominators, we get:

10 + 5 = 2x

15 = 2x

Dividing both sides by 2, we find:

x = 7.5

Therefore, it will take the newer computer 7.5 minutes to send out the email on its own.
