In the first scenario, the rate of work is   =   job per day per worker.


In the second scenario, the rate of work is   =   job per day per worker,

where "d" is the unknown number of days.



The rate of work is assumed to be the same in both cases, which produces this equation


     = .


From this equation (from this proportion)


    15*d*p = 50*k,


    d =  = .    ANSWER
