Question

When the summer started, Janie needed to fill her empty pool. At first, she used a garden hose to fill the pool, but this was taking too long. She got tired of watching the pool fill so slowly, so she turned off the water and went for a walk. She spotted a truck in the neighborhood that was filling pools and flagged them down to come fill her pool too. They were able to fill the pool at a faster rate. Which graph best represents this situation?

Answer 1

The statement mentions that the pool started empty, which implies that the graph must start at the point (0,0).

Then, the pool slowly filled, so the amount of water in the pool remained constant when Janie turned off the water and went for a walk.

Finally, thanks to a truck in the neighborhood the pool filled up quickly, and when it was filled the amount of water remained constant.

Therefore, the graph that best represents this situation is the one shown in option B.
