you have a barrel with water. after 30 seconds there is 14 gallons left. one minute you have 9 gallons left. determine the time the barrel was empty.

• Math -

If after 30 seconds there are 14 gallons left, and after 60 seconds there are 9 gallons left,

Then you can see that in the 30 second gap, 5 gallons leaked out. So water is emptying at 5 gallons/30 seconds or 1 gallon every 6 seconds.

Can you use this rate of emptying and the initial number of gallons given to find the time?

i am getting 35 min and 7 sec. is that right?

No. How can you get more than a half hour for 9 gallons when 1 gallon is emptied every 6 seconds?
