I'm having trouble understanding this word problem.
A construction worker drops a bolt while woring 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, o < t < 8
a. Find the average velocity during the first, third and eighth seconds.
I have to use f(x + h) - f(x)/h
I got 5(t +h)
The answer is 5m/s for the first one.
How do I get the rest of them (third and eighth second)?
