Question

Use the image to answer the question.

A line is graphed on a coordinate plane.

A water tank is being slowly emptied to remove it and replace it with another one. The graph shows the declining water level of gallons in hours. Approximately how long will it take for the water tank to be emptied?

Responses

35 hours

11.7 hours
11.7 hours

−3
hours
negative 3 hours

12 hours

Answer 1

To determine how long it will take for the water tank to be emptied based on the graph provided, we need to look at the x-axis (representing time in hours) and the y-axis (representing the gallons of water).

As we cannot see the graph, you would typically look for the point where the line intersects the x-axis, as this will indicate when the water level reaches zero gallons.

Assuming you are able to observe the graph, here is how you can interpret the results:

- If the line intersects the x-axis at around 11.7 hours, then the answer would be **11.7 hours**.
- If it intersects around 12 hours, then the answer would be **12 hours**.
- If it intersects at 35 hours, then the answer would be **35 hours**.
- A negative time (like −3 hours) would be illogical in the context of this problem.

Please compare the options based on your observation of the graph to find the correct answer.
