There were 33,300 fatalities in 2015. how many deaths is that per hour ?

Hi! 

So for this problem you need to know how that there are 8,760 hours in a year. If we're trying to find how many deaths there were per hour, you'd need to divide 33,300 by 8760 to find out.

33,300/8760=3.80136986301

This means there were roughly 3.8 deaths per hour. 

Hope this helps :)
