Answer
**a. U.S. Data:*** **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.* **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.**b. Global Data:*** **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.* **Injuries:** With 44 million injuries globally per year, a person is injured approximately every 31,536,000 / 44,000,000 ≈ 0.7 seconds.**Answers for fill-in-the-blanks:*** Globally, a person is killed in a car crash about one time every **17.5** second(s).* Globally, a person is injured in a car crash about one time every **0.7** second(s).
