        In the post by @mananth, the internal calculations are presented in wrong form

        and can scare/confuse a reader.  So I came to make a job as accurately as it should be done.



<pre>
Joanne makes 1/40 of the job per minute.

Hope makes 1/50 of the job per minute.


Working together, the make  

    {{{1/40}}} + {{{1/50}}} = {{{5/200}}} + {{{4/200}}} = {{{9/200}}}

of the gob per minute.


Hence, they need  {{{200/9}}} = 22{{{2/9}}}  minutes to complete the job working together.


<U>ANSWER</U>.  The need 22{{{2/9}}} minutes to complete the job working together.

Solved correctly and presented in the normal form as it should be done.
