Answer:

4 hours

Explanation:

In 6 hours, J paints 1 room

So, in 1 hour, J paints 1/6 th of the room

Using similar logic, in 1 hour, T paints 1/12 th of the room.

Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.

1/4 of the room is painted in 1 hour

So, 1 room is painted in 1 1/4=4 hours
