It's given in this question that the number of traffic deaths in 1992 was 39 ,250, and in that year, motor vehicles traveled 2 ,247 billion miles.
00:18
And in 2002, it was 42 ,815 traffic accidents resulting in death, and in that year, 2 ,830 billion miles had been traveled by vehicles.
00:34
And so we are asked to report the deaths per 100 million miles traveled.
00:44
So if we look at 1992, we have 39 ,250 deaths per 2 ,247 billion miles.
01:07
A billion is 10 to the exponent 9.
01:17
And if we do this calculation, we get 1 .75 times 10 to the minus 8 deaths per mile.
01:29
So if we have this many deaths in one mile, then in 100 million miles we're going to have 1 .75 times 10 to minus 8 times 100 million for 100 million miles...
