Question
There are two different vats the first that has 12 gallons and is being filled at the rate of 3 gallons per minute the second that has 100 gallons and is leaking fluid at the rate of 2 gallons per minute. How many seconds both bats have the same amount of liquid.

To find the time when both vats have the same amount of liquid, we can set up equations for the amount of liquid in each vat over time.
1. **First vat**:
- Initial amount of liquid = 12 gallons
- Filling rate = 3 gallons/minute
- Amount of liquid after \( t \) minutes:
\[
V_1(t) = 12 + 3t
\]
2. **Second vat**:
- Initial amount of liquid = 100 gallons
- Leaking rate = 2 gallons/minute
- Amount of liquid after \( t \) minutes:
\[
V_2(t) = 100 - 2t
\]
To find when both vats have the same amount of liquid, we set \( V_1(t) \) equal to \( V_2(t) \):
\[
12 + 3t = 100 - 2t
\]
Now, we can solve for \( t \):
1. Combine like terms:
\[
3t + 2t = 100 - 12
\]
\[
5t = 88
\]
2. Solve for \( t \):
\[
t = \frac{88}{5} = 17.6 \text{ minutes}
\]
To convert minutes to seconds:
\[
t = 17.6 \text{ minutes} \times 60 \text{ seconds/minute} = 1056 \text{ seconds}
\]
Thus, both vats will have the same amount of liquid after **1056 seconds**.
