Irina:
---------------------------------------------------------------------------
Irina takes 7 hours to paint the room.
In 1 hour, Irina can paint 1/7 of the room.
---------------------------------------------------------------------------
Paulo:
---------------------------------------------------------------------------
Paulo takes 6 hours to paint the room.
In 1 hour, Paulo can paint 1/6 of the room.
---------------------------------------------------------------------------
Both paint together:
---------------------------------------------------------------------------
In one hour they can paint (1/7 + 1/6) of the room.
1/7 + 1/6 = 13/42
So, it takes 13/42 of the room takes 1 hour.
---------------------------------------------------------------------------
Find the number of hours
---------------------------------------------------------------------------
13/42 of the room = 1 hour
Whole room = 1 ÷ 13/42
Whole room = 1 x 42/13
Whole room = 3.23 hours
---------------------------------------------------------------------------
Answer: They need 3.23 hours to paint the room.

Then the first number is 22+6=28
The third number is 4 times the second 22*4=88
28+22+88 = 138
Answer:
102 ft.
Step-by-step explanation:
See the diagram attached.
From right triangle Δ ADC,
⇒ AC = 160 ft. {Since 
}
Now, given that BC = 42 ft.
Hence, AB = AC - BC = 160 - 42 = 118 ft.
Now, from right triangle Δ AEB we can write
⇒ 
ft ≈ 102 ft.
Therefore, the closest distance from point A on one bank to point E on the opposite bank is 102 ft. (Answer)
