compute the average velocity of a stone over time intervals

1, 1.01
1, 1.001
1, 1.0001
and
.99,1
.999,1
.9999,1.
use this to estimate instantaneous velocity at t=1
All i can figure out the formula should be s(t1)-s(t0) over t1-t0
how does that give you a number what am i missing

Without the definition of S(t), we are not able to do the required calculations.
