40 chapatimakers work at a rate of 10 chapos/hr. 2 chapatimakers will work at a rate of (2*10)/40 = 0.5 chapos/hr. They will therefore take 10/0.5 hrs = 20 hours. -- Thanks and Regards, Erick Njenga Nyachwaya, M: +254-725-008-790 <http://www.facebook.com/ErickNjenga> <http://www.twitter.com/ErickNjenga>
