What Is the Average Reading Rate for Beth's Day?

[QUOTE="RUber, post: 5499140, member: 524408"] You have found total time and the total number of pages is pretty straightforward. Average rate (pages/hour) is defined as (total pages) / (total hours). As Mark pointed out, it is not (rate1 + rate2)/2. If you wanted to find average time, do you mean hours per page? That is the inverse of your rate (given in pages/hour). So, you could get to the answer that way since the number of pages read is the same. avg. time = (time1+time2)/2. Your average rate would be 100 pages / average time. A little algebra will show you that these equations are consistent. However, if you have different # of pages at each rate, the second method falls apart while the (total pages) / (total time) method still works. [/QUOTE]
