CPM Homework Help : APCALC Problem 9-24

Betsy accelerated quickly from a stop sign at the freeway entrance. A table of her velocity is shown below. Approximate how far she went in the first $10$ seconds using a trapezoidal approximation with subintervals of $dt = 2$ seconds.

Time (sec)	Vel. (ft/sec)
$0$	$0$
$2$	$19$
$4$	$36$
$6$	$52$
$8$	$70$
$10$	$84$

Step:

$\frac{1}{2}(2)(0+19)+\frac{1}{2}(2)(19+36)+\frac{1}{2}(2)(36+52)+...$
