Question 1122725
.
In order to be correct,


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;the condition &nbsp;MUST &nbsp;SAY &nbsp;&nbsp;"how long it would take them <U>TO DO WHAT ?</U> &nbsp;if they worked together".



So take the labor to formulate the condition correctly.



Please. And thank you.

    Looking on the @josgarithmetic efforts, I am wondering every time, 


    how this person, who can not practically solve correctly any problem, 


    is ready to solve enthusiastically even incorrectly formulated problems ! !
