A construction worker drops a bolt while working on a high-rise building 320m above the ground. After t seconds, the bolt has fallen a distance of s metres, where s(t) = 320-5t^2, 0 <= t <=8

Find the average velocity for the interval 3<=y<=8

2. Relevant equations

3. The attempt at a solution

I used the formulas [tex]\Delta[/tex]s / [tex]\Delta[/tex]t

which then =

s(8) - s(3) / (8-3)

=55

Is this right?
