Rufus appears before Bill and Ted and offers them a bogus proposition: they must paint a house together with their magical guitars in a mere 5 hours. Ted, who is tired, knows that the fastest he can solo rock the paint job through the strings of his guitar is 19 hours. How hard does Bill have to jam to ensure the house is completed in time?
