Question

Calculus I Problem:
The table shows the position of a cyclist.
t (seconds) 0 1 2 3 4 5
s (meters) 0 1.4 5.2 10.6 17.7 26.2

--> Estimate the instantaneous velocity when t = 3.

Answer 1

What you need to do, @suzumiisama is you need to find the average velocity between t=2 and 3, find the average velocity between t=3 and 4 and average that. In other words, assuming this is a function \(s(t)\), your equation would be something like this:
\[\frac{\frac{s(3)-s(2)}{3-2}+\frac{s(4)-s(3)}{4-3}}{2}\]

Answer 2

Yay i got it :) Thanks so much

Answer 3

My pleasure :)
