Assume a car on the highway travels at an average speed of 100 km/h. Based on FAR data, how many kilometers are driven before a fatality is expected? A large plant has 1500 full time employees. If the plant has an average FAR of 5, how many fatalities are expected each year? Suppose a plant has a FAR of 2. On average, its employees spend 1 hour by car commuting to and from work (1 hour total; 30 minutes each way). Which activity do you expect to result in more fatalities, travelling to work, or the actual work? Determine the fatalities per person per year for each activity
