Katy is walking on a path, moving towards a bridge. The table represents a function [tex]\( f \)[/tex] that describes Katy's distance from the bridge, in meters, after [tex]\( x \)[/tex] minutes of walking.

[tex]\[
\begin{tabular}{|c|c|}
\hline
$x$ & $f(x)$ \\
\hline
0 & 300 \\
\hline
1 & 250 \\
\hline
2 & 200 \\
\hline
3 & 150 \\
\hline
4 & 100 \\
\hline
5 & 50 \\
\hline
6 & 0 \\
\hline
\end{tabular}
\][/tex]

Select the correct statement:

A. Katy was initially 300 meters from the bridge, and it took her 5 minutes to reach the bridge.

B. Katy was initially 300 meters from the bridge, and it took her 6 minutes to reach the bridge.

C. Katy was initially 250 meters from the bridge, and it took her 5 minutes to reach the bridge.

D. Katy was initially 250 meters from the bridge, and it took her 6 minutes to reach the bridge.

To solve this problem, let's analyze the information provided in the table and determine which statement correctly describes Katy's walk towards the bridge.

The table gives us the following data points:

[tex]\[ \begin{tabular}{|c|c|} \hline x & f(x) \\ \hline 0 & 300 \\ \hline 1 & 250 \\ \hline 2 & 200 \\ \hline 3 & 150 \\ \hline 4 & 100 \\ \hline 5 & 50 \\ \hline 6 & 0 \\ \hline \end{tabular} \][/tex]

1. Initial Distance:
[tex]\[ f(0) = 300 \][/tex]
This tells us that initially, i.e., at [tex]\( x = 0 \)[/tex] minutes, Katy was 300 meters away from the bridge.

2. Consistency of Decrease:
[tex]\[ \begin{aligned} f(1) &= 250 \quad \text{(after 1 minute)}, \\ f(2) &= 200 \quad \text{(after 2 minutes)}, \\ f(3) &= 150 \quad \text{(after 3 minutes)}, \\ f(4) &= 100 \quad \text{(after 4 minutes)}, \\ f(5) &= 50 \quad \text{(after 5 minutes)}, \\ f(6) &= 0 \quad \text{(after 6 minutes)}. \end{aligned} \][/tex]

We see that the distance decreases by 50 meters each minute consistently.

3. Reaching the Bridge:
[tex]\[ f(6) = 0 \][/tex]
This indicates that after 6 minutes, Katy reaches the bridge as her distance from it becomes 0.

With this analysis, let's evaluate the given statements:

- A. Katy was initially 300 meters from the bridge, and it took her 5 minutes to reach the bridge.
This is incorrect because it took her 6 minutes, not 5 minutes, to reach the bridge.

- B. Katy was initially 300 meters from the bridge, and it took her 6 minutes to reach the bridge.
This is correct according to our analysis.

- C. Katy was initially 250 meters from the bridge, and it took her 5 minutes to reach the bridge.
This is incorrect because she started 300 meters away, not 250 meters.

- D. Katy was initially 250 meters from the bridge, and it took her 6 minutes to reach the bridge.
This is incorrect for the same initial distance reason as in C.

Thus, the correct statement is:
[tex]\[ \boxed{B} \][/tex]
Katy was initially 300 meters from the bridge, and it took her 6 minutes to reach the bridge.
