    11.413 Hours.

    Step-by-step explanation:

    Alicia can paint a house in 21 hours; Which means in 1 hour she can paint 1/24 of the house.

    Nina can paint the same house in (21+4) hours. Which means in 1 hour she can paint 1/25 of the house.

    Together in 1 hour they can paint: 1/21 + 1/25 = 46/525 of the house.

    Total Hours for painting the house together will be 525/46 = 11.413 Hours.
