To find out how many minutes it will take to empty the pool, we need to determine when the amount of water \( w \) in the pool equals zero.
We start with the equation provided:
\[
w = 45,000 - 100t
\]
We set \( w \) to zero to find \( t \):
\[
0 = 45,000 - 100t
\]
Now, we can solve for \( t \):
\[
100t = 45,000
\]
\[
t = \frac{45,000}{100}
\]
\[
t = 450
\]
So, it will take 450 minutes to empty the pool.
