Best ResponseYou've already chosen the best response.1You need to get one work done. You cannot talk in terms of time.........You have to talk in terms of how much work is done Thats why...................Lets say I do the work in A minutes. U spoil the work in B minutes..............>>>>>So in unit time we do (1/A1/B) work together. right ?? Now we know how much work we accomplish in unit time............so u can find out how much time we shall need to get the work done ;)
