Answer:

The crash rate is 22 vehicles per 1 million vehicles

Explanation:

In this question, we are asked to determine the crash rate per million vehicles.

Crash rate is calculated using average crash frequency.

The crash rates are calculated based on the number of crashes per million vehicle miles travelled in a year.

Mathematically;

crash rate = (48 * 1,000,000)/ [(980 + 1560 + 1230 + 900 + 1435)* 365]

= 48,000,000/(6105*365)

= 21.54 approximately 22
