Three typists working 8 hours a day type a document in 10 days. If only 2 typists are working, how many hours a day should they work to finish the job in 12 days.
Answered by Steve
the job takes 3*8*10=240 typist-hours.

2 typists working x hours per day perform 2x typist-hours per day.

So, 2x*12 = 240
x = 10 hours per day
