Answer :
It takes the faster computer 70 minutes to do the job on its own.
To solve this problem, we can use the formula for solving for the time it takes two people working together to complete a task:
Time = (Time of slower worker * Number of workers) / (Number of workers - 1)
This formula is based on the idea that the slower worker determines the overall time it takes to complete the task, and the faster worker helps to reduce the overall time. The formula takes into account the time that the slower worker takes to complete the task on their own, as well as the number of workers involved.
In this case, we are given that it takes the slower computer 35 minutes to do the job on its own, and that it takes the two computers working together 10 minutes to send out the company's email. We can plug these values into the formula as follows:
Time = (35 minutes * 2) / (2 - 1)
= 70 minutes / 1
= 70 minutes
