In order to be correct,

        the condition  MUST  SAY   "how long it would take them TO DO WHAT ?  if they worked together".


So take the labor to formulate the condition correctly.


Please. And thank you.

BUSHELS per HOURS, rate

Both working together, 40%2F8%2B40%2F9

5%2B40%2F9

45%2F9%2B40%2F9

85%2F9, bushels per hours

How much time, for 40 bushels?
%289%2F85%29%2A40
9%2A8%2F17


4 hours and 14 minutes
or
4.24 hours
