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) $0$ $0$ $2$ $19$ $4$ $36$ $6$ $52$ $8$ $70$ $10$ $84$

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