Answer:
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.
