David walked 19 kilometers. The first part of the walk was at 5kph and the rest at 3kph. he would have covered 2 kilometers less if he had reversed the rates, that is, if he had walked at 3kph and at 5kph for the same times that he actually walked at 5kph and 3kph, respectively. How long did it take him to walk the 19 kilometers?
