Question

In 2009, about 1 in __________ alcohol-impaired crash fatalities were age 65 or older.

A. 5
B. 14
C. 22
D. 100

Answer 1

Answer:

C. 22

Explanation:

In 2009, total fatal crashes of the group that aged 65 or more was 5,418. Out of which 284 were due to alcohol-impaired crash fatalities. Calculation as below:

284/5418*100= 5.24% approximately rounding off or 1 in 20 fatal crashes due to alcohol aged 65 or more.

However, some 676 drivers died due to fatal crashes whose age were unknown. Assuming if they were aged 65 or more and died due to any reason other than alcohol. The calculation will be as follows:

284/(5418 + 676)*100= 4.66% approximately rounding off or 1 in 22 fatal crashes due to alcohol aged 65 or more.

Hence, the answer C.22 is correct.
