Question 1055859
Work Rates Description.
RT=J relates rate, time, amount of jobs or amount of job.  The example uses rate unit of acres per day.


Use the description and rate rule to fill a data table.

<pre>
                   RATE           TIME         JOB

DONE                60            t-1           1

PLANNED             50             t            1
</pre>

"The task", is 1 whole job, and that is what the description discusses.  We do not know how many acres is in ONE JOB, but we know that the DONE and the PLANNED are for this one job.  


(Actually, may be better to give a variable instead of saying "1" job.)


{{{60(t-1)=1=50*t}}}
The obvious equation.
Solve for t, and use it for the "planned" part of the description to find how many acres was the one job.
