Hi All,
I am given the first two columns and asked to find the maximum hourly precipitation in inches/hr.
The last two columns are part of the solution. I'm not really understanding their solution so would anyone please explain why the cumulative values need to be taken? Also, it seems they didn't add the cumulative values correctly either?
