How do find the average velocity using 5 subintervals and midpoints?
   time(t): 0  1      2     3     4     5     6     7     8     9      10

break the time interval into 5 parts:  10/5 = 2


|-------|--------|-------|-------|--------|
0   1      2     3     4     5     6     7     8     9     10
0  20    35   48   62   75   85   93   99  106   111
     ^              ^            ^            ^           ^
                  midpoints maybe?

add up the midpoints and divide by 5 is my guess
