Question

erica is learning to drive, so her dad took her to a large, empty parking lot where she can practice. erica slowly starts driving, accelerating until she reaches and maintains a good speed. halfway across the lot, she stops briefly to practice braking. then, she repeats the process: accelerating, finding a good constant speed, and slowly coming to a stop. which graph could show ericas speed over time?

Explanation:

Step1: Analyze Erica's driving process

Erica starts driving, accelerates (speed increases), then maintains a constant speed (speed stays the same), then stops briefly (speed drops to 0 briefly), then repeats: accelerates (speed increases), constant speed (speed stays same), then stops (speed drops to 0).

Step2: Evaluate each graph

• Top - Left: Speed increases, then constant, then decreases to 0. No brief stop (speed doesn't drop to 0 in the middle), so incorrect.
• Top - Right: Speed increases, constant, drops to 0 (brief stop), then increases, constant, drops to 0. Matches the process.
• Bottom - Left: Speed increases, then decreases (no constant speed or brief stop), incorrect.
• Bottom - Right: Speed increases, then decreases (not a brief stop, and the middle dip isn't a stop at 0), incorrect.

Answer:

The Top - Right Graph
