CPM Homework Help : PC Problem 9-37

Now we want to calculate the average velocity of our toy car (with $d\left(t\right) = 10t^{2}$ ). Find the average velocity on each of the intervals.

$[4, 5]$
Step (a):
$\frac{\Delta d}{\Delta t} = \frac{d(5) - d(4)}{5 - 4}$

$[4, 4.1]$
Step (b):
$\frac{\Delta d}{\Delta t} = \frac{d(4.1) - d(4)}{4.1 - 4}$

$[4, 4.01]$

$[3.99, 4]$

$[3.999, 4]$
