Afresh water tank shaped like a rectangular prism has a length of 72 in. a width of 24 in. and a height of 25 in. the tank is filled with water at a constant rate of 5 cubic feet per hour. how long will it take to fill the tank half way?me ✌

First, you have to find the volume of the whole tank. Length times width times height in the case, would equal 43200 cubic feet. Then, because it is half the tank, we divide that in half, to get 21600.  If it takes 1 hour to fill 5 cubic feet, we divide 21600 by 5. This shows that it would take 8640 hours to fill.

Present age of john= 24 years

Let Shane's age= x years

 Two years ago

John's age = 24-2= 22 years

Shane's age = (x-2) years

  Writing in terms of equation,to the above statements

⇒22= 2(x-2)

⇒22= 2 x- 4

⇒22+4 = 2 x

⇒ 2 x= 26

⇒ x= 26÷2

⇒ x =13

Present age of son = 13 years
