You can put this solution on YOUR website! a tank can be normally filled in 10 hours. but after the tank developed a leak it took 12 hours to fill it. how long would it take the leak to empty a full tank?
:
Let t = time for the leak to empty the tank
:
Let the full tank = 1
:
Positive is filling and negative is leaking
: - = 1
:
Multiply equation by 10x to get rid of the denominators
10x() - 10x() = 10x*1
:
12x - 10(12) = 10x
:
12x - 120 = 10x
:
12x - 10x = + 120
:
2x = 120
:
x = 120/2
:
x = 60 hrs for leak to empty the full tank
:
:
Check our solution on a calc: - =
1.2 - .2 = 1
:
Did this make sense to you?
