Question

sonya made a graph showing the first ten minutes of her drive to the movies. which description is the best interpretation of the graph?
○ sonya left her house and accelerated as she drove toward the highway entrance. she increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
○ sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. she stopped the car.
○ sonya drove down her driveway at a constant speed until she reached the street. she turned and drove down the street at a constant speed. her car went slower as she drove up a hill. at the top of the hill she drove into the parking

Explanation:

• Analyze the graph (speed - time): The first part shows increasing speed (acceleration), then a steeper increase (more acceleration, like on a ramp), then constant speed (flat line).
• Option A matches: Initial acceleration (leaving house), increased speed (ramp), constant speed (highway).
• Option B: "backed out... constant speed" doesn't match the increasing speed start, and "stopped" isn't shown (graph has constant speed, not zero).
• Option C: Mentions "slower as she drove up a hill" (deceleration), but graph has acceleration then constant speed, no deceleration.

Answer:

A. Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
