Final answer:
The teenage collision rate per mile is generally higher than the adult driver collision rate per mile due to factors such as inexperience and risk-taking behavior.
Step-by-step explanation:
The teenage collision rate per mile is x times greater than the adult driver collision rate per mile.
To determine the value of x, we need specific data on the teenage and adult driver collision rates per mile. Without that information, we cannot calculate the exact value.
However, studies have shown that teenage drivers are more likely to be involved in car accidents compared to adult drivers. This is due to factors such as inexperience, risk-taking behavior, and distractions. Therefore, it is generally accepted that the teenage collision rate per mile is higher than the adult driver collision rate per mile.
