The position of a person is given by x = 5t - 0.4t2, where x is in meters and t is in seconds. What is the average velocity between t = 0 s and t = 8 s? (m/s)
What is the average velocity between t = 8 s and t = 10 s? (m/s)
What is the average velocity between t = 8 s and t = 10 s? (m/s)

the average speed over any interval [a,b] is just
f(b)-f(a)
---------------
b-a
So just plug in your numbers.
f(b)-f(a)

b-a
So just plug in your numbers.
