Sally can paint a house in 4 hours; Which means in 1 hour she can paint 1/4th of the house.
John can paint the same house in 6 hours. Which means in 1 hour she can paint 1/6th of the house.
Together in 1 hour they can paint: - 1/4 + 1/6 = 5/12th of the house.
Total Hours for painting the house together will be 12/5 = 2.4 Hours.
