Question

A water tank holds 675 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 900 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

Answer 1

It will take approximately 20.454545454545455 weeks for the amount of water in the two tanks to be the same.

Explanation:

To find the number of weeks it will take for the amount of water in the two tanks to be the same, we can set up the following equation:

675 - 4w = 900 - 7w

Then, we can solve for w by adding 4w to both sides and then adding 7w to both sides:

11w = 225

w = 225 / 11

thus, It will take approximately 20.454545454545455 weeks for the amount of water in the two tanks to be the same.
