I cant understand why are we not finding avg time?

## Homework Equations

S= v * t

## The Attempt at a Solution

First find the total time.

Pages = 100, v= 60 pages per hour: S = v* t; 100= 60 *t; t= 100/60= 5/3

Pages = 100, v = 40pages per hour: S = v* t; 100= 40 *t; t= 100/40= 5/2

Total Time = 5/2 + 5/3= (15 + 10)/6 = 25/6

At this point my question is why are we not finding average time? We have to find average rate of reading. So we must find average time??

Some body please guide me.
