Final answer:
Cheryl's commute varies depending on traffic conditions.
Step-by-step explanation:
The statement that best describes Cheryl's commute is option d: Cheryl's commute varies depending on traffic conditions. This means that Cheryl's commute is not consistently long or short, tiring or enjoyable, or made easier with public transportation, but rather changes based on the level of traffic congestion.
For example, on days with heavy traffic, Cheryl's commute may be longer and more tiring, while on days with lighter traffic, her commute may be shorter and more enjoyable. The variability in her commute is directly related to the traffic conditions on the roads she takes.
Therefore, option d is the most accurate and appropriate description of Cheryl's commute.
