Use the following data to answer the questions U.S. data (estimates for a Aast year : car crash istal ties=47,000; iriumies -4.5 million; co st to socichy= 400 billion Global data (estimates for a past year): car crash fratalities approx 1.8 millian, iriguries approx 44million deaths under age 25approx 400,000 a. About how often (once eveny x minutes or x seconds) on average is a person killed in a car crash in the United States? How often is a person injured in a car crash? b. Repeat part (a)for the global data (kound to the nearest tenth as needed.) b. Glohally, a person is killed in a car crash about one time every square seconds(s) (Round to the nearest tenth as needed.) Globally, a person is injured in a car crash about one time every square seconds(s) (Round to the nearest tenth as needed.

**a. U.S. Data:**<br /><br />* **Fatalities:** There are 60 minutes in an hour, 24 hours in a day, and 365 days in a year. So there are 60 * 24 * 365 = 525,600 minutes in a year. If there are 47,000 car crash fatalities per year, then on average, a person is killed every 525,600 / 47,000 ≈ 11.2 minutes.<br /><br />* **Injuries:** Using the same logic as above, there are 31,536,000 seconds in a year (525,600 minutes * 60 seconds/minute). If there are 4.5 million injuries per year, then on average, a person is injured every 31,536,000 / 4,500,000 ≈ 7.0 seconds.<br /><br /><br />**b. Global Data:**<br /><br />* **Fatalities:** Using the 31,536,000 seconds in a year and 1.8 million fatalities, a person is killed globally approximately every 31,536,000 / 1,800,000 ≈ 17.5 seconds.<br /><br />* **Injuries:** With 44 million injuries globally per year, a person is injured approximately every 31,536,000 / 44,000,000 ≈ 0.7 seconds.<br /><br /><br />**Answers for fill-in-the-blanks:**<br /><br />* Globally, a person is killed in a car crash about one time every **17.5** second(s).<br />* Globally, a person is injured in a car crash about one time every **0.7** second(s).<br />
