Unsure if you want this as a inverse variation problem or as a uniform rates problem.
As written, n for count of workers, t for time in hours,
is the translation of the first sentence.
Second sentence, first part, after solving the formula for k,
The variation formula can now be more specifically given as .
Third sentence, n=25, t is unknown. Find t.
hours
