A company has two large computers. The slower computer can send all the company's email in 55 minutes. The faster computer can c
omplete the same job in45 minutes. If both computers are working together, how long will it take them to do the job?
1 answer:
You find the rates of each computer on its own...
One does the job in 55 minutes which we can say is 1/55
The other has a rate of 1/45.
The question wants to know how long it would take both working simultaneously to complete the job...
t/55+t/45=1
(9t+11t)/495=1
20t=495
t=24.75 minutes (24:15)
