1 hour = 1/5 of the house

1 hour = 1/3 of the house.

Both together,
1/3+1/5 = 8/15 of the house in 1 hour.

1/15 of the house in 1/8 hours

15/15 of the house in 1/8 x 15

= 15/8 hours

= 1.875 hours.

They both can paint the house in 1.875 hours.

That's a good question also interesting.

I suppose that would be less than 3 hours, but it depends.
