emily lives in a third - floor apartment. this morning, she walks downstairs to go to school. when she reaches the bottom of the stairs, she realizes that she forgot her spanish book! she rushes upstairs, quickly grabs the book, and then races back down again. which graph could show emilys height above the ground over time?
Answer
Explanation:
Step1: Analyze Emily's movement
Emily starts at a certain height (third - floor), walks downstairs (height decreases), then rushes upstairs (height increases), grabs the book, and races back down (height decreases again).
Step2: Check the first graph
In the first graph, the height first increases (which is not in line with Emily first walking downstairs).
Step3: Check the second graph
In the second graph, the height starts at a higher value (representing the third - floor), then decreases (walking downstairs), then increases (rushing upstairs to get the book), and then decreases again (racing back down to school).
Answer:
The second graph.
