Question 946611: How can I set up a related equation with the given information:
"Water started leaking from a tank at noon and continued leaking at a constant rate for the next 6 hours. The volume of water in the tank at 6pm was 1/4 of the volume of water in the tank at noon. Find an equation that relates.
Where g = the number of gallons of water in the tank at noon,
t= the number of hours after noon
h = the number of gallons of water in the tank at t hours after noon"
Thanks!

You can put this solution on YOUR website! You are showing that you want this equation to be all in symbols, or almost all in symbols.
The leakage rate is  , or the ratio of the amount of volume leaked to the time that the leaking occurred. Simplified, that is  or  . Before continueing this way, I am changing to 6=t, because otherwise I would confuse the further uses of the variables, including t. I am now choosing to use the known given constant value. The leak rate is  .
This uniform rates problem seems to be a fairly simple linear equation application. For time t=0, the volume in the tank is h=g.
For time t=6 or anything more than zero (as long as not too large), the volume in the tank becomes  .
Here,  is a variable, greater than or equal to zero and less than or about equal to 8 hours. After about 8 hours, the tank would become empty, so no more leaking.
