Let t be the time for Paul to do the job alone.
_______________work rate________time__________job
Ron___________(___)_____________t+2___________1
Paul__________(___)______________t____________1
Together______(___)______________5_____________1
Rate*Time=Job, fill in the missing rate information.
_______________work rate________time__________job
Ron___________1/(t+2)_____________t+2___________1
Paul__________1/t_________________t____________1
Together______1/5_________________5_____________1
The rates of both working together are simply additive. Solve for t. Use it to compute each person's rate.
