A water tank holds 248 gallons but is leaking at a rate of 3 gallons per week. A second water tank holds 372 gallons but is leaking at a rate of 5 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

Let the number of weeks when the 2 tanks equalize =W

 

248 - 3W =372 - 5W, solve for W

5W - 3W =372 - 248

2W = 124

W = 124 / 2

W = 62 weeks - when both tanks will be the same.
