Question

eli left his house one afternoon to study at the library. the graph shows his distance, in miles, away from his house as a function of time, in minutes. elis trip to the library what could explain what happened when the time was equal to 120 minutes? eli arrived at the library. eli rode his bicycle home from the library. eli rode his bicycle to the store, getting farther away from his house. eli continued to study at the library for 13 more minutes.

Explanation:

To determine what happened at 120 minutes, we analyze the graph. The y - axis represents distance from home, and the x - axis represents time. Before 120 minutes, the distance was constant (around 4 miles, meaning he was at the library). At 120 minutes, the distance starts to decrease rapidly towards 0, which indicates he is moving back towards his house.

• Option 1: If he arrived at the library, the distance would stop increasing, not start decreasing.
• Option 2: When he rides home from the library, his distance from home should decrease, which matches the graph's behavior at 120 minutes.
• Option 3: If he went to the store, distance would increase, but it's decreasing.
• Option 4: Continuing to study would keep distance constant, not decrease.

Answer:

B. Eli rode his bicycle home from the library.
