Homework question: How deep is the shallow and deep end of a swimming pool?

Question

I am not sure if my answer is right. The graph shows how the depth of water in a swimming pool increases when water is pumped in at a constant rate.

Question: Assuming the pool was full after 50 minutes, how deep was the shallow end? How about the deep end?

My answer is 1 meter for the shallow end and 2.5 meters for the deep end. But I am not sure if my answer is correct.

Here's the graph:

The y-axis is depth in meters and the x-axis is time in minutes.

Answer 1

Your answer is incorrect. The deep end is $2.5 \ \text m$ deep and the shallow end is $1.5 \ \text m$ deep.
