Question

Katy is on a path, moving towards a bridge. The given table represents a function that describes Katy’s distance from the bridge, in meters, after x minutes of walking.

A. Katy was 250 meters from the bridge, and it took her 5 minutes to reach the bridge.
B. Katy was 250 meters from the bridge, and it took her 6 minutes to reach the bridge.
C. Katy was 300 meters from the bridge, and it took her 5 minutes to reach the bridge.
D. Katy was 300 meters from the bridge, and it took her 6 minutes to reach the bridge.

Answer 1

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

Explanation:

Recall that x represents the time walked

When you see the first entry on the table as: x=0, that means Katy is about to start her walk, and the value to the right which represents her distance from the bridge is 300 meters. So as her walk started she was 300 meters from the bridge.

Now look at the last entry pair at the bottom of the table: the value in the "x" column (that represents the number of minutes she walked) reads: 6, and the value to the right (next column) reads 0 (0 meters from the bridge)

This is telling us that Katy was at the bridge after 6 minutes of walk. So answer D is the correct answer representing the given table of time and distance values.
