    Answer:

    Scenario 1: Assume that you paint a room by yourself in four hours.

    Then your friend would take eight hours.

    Scenario 2: If it took both you and your friend 4 hours to paint a room, then that means that you would have taken approximately 1.3 hours and your friend approximately 2.6 hours to paint that specific room.
