Explanation:

The graph shows speed over time. The speed increases to 65 mph in the first part (acceleration), stays at 65 mph for a horizontal - line segment which represents constant speed (from 1 to 6.5 minutes, so 5.5 minutes), and then decreases (deceleration) to 45 mph.

Answer:

A. Cheryl accelerated to 65 mph, drove at a constant speed for 5.5 minutes, and then decelerated to 45 mph.
