Question 477378: A man builds a chair in 4 days, working 6 hours a day. How many hours should he work in a day if he wants to build it in 3 days? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! The number of chairs n built is directly proprtional to the number of hours worked in a day h, and to the number of days d worked.
==> n = kdh
==> 1 = k(4)(6) ==> k = 1/24
==>
==> ==> d = 8, the number of days.
