Question 357890
Working together, it takes two computers  10 minutes to send out a company’s email. If it takes the slower computer 35 minutes to do the job on its own, how long will it take the faster computer to do the job on its own?

...
both computers do the job in 10 minutes
so they do 1/10 of the job in 1 minute
...
slower computer does in 35 minutes
it does 1/35 of the job in 1 minute.
1/10-1/35 
=35-10 / 350 
25/350 of the job the faster one does in 1 minute
It takes 350/25 minutes to do the job for the faster one
=14 minutes
