We are given data for $$ t $$ and $$ v $$ and need to approximate the total distance traveled from 0 to 8 seconds using the trapezoidal rule with $$ n=4 $$ subintervals.

Since the interval is from 0 to 8 seconds, the width of each subinterval is

$$
h = \frac{8-0}{4} = 2.
$$

The trapezoidal rule formula for approximating the integral is

$$
I \approx \frac{h}{2} \left[ f(t_0) + f(t_n) + 2\sum_{k=1}^{n-1} f(t_k) \right],
$$

where $$ f(t) $$ is the velocity at time $$ t $$.

We choose the points corresponding to $$ t = 0, 2, 4, 6, 8 $$ seconds. From the table:

- At $$ t=0 $$: $$ v = 0 $$
- At $$ t=2 $$: $$ v = 9 $$
- At $$ t=4 $$: $$ v = 17 $$
- At $$ t=6 $$: $$ v = 20 $$
- At $$ t=8 $$: $$ v = 26 $$

Substitute these values in the formula:

$$
I \approx \frac{2}{2} \left[ 0 + 26 + 2(9 + 17 + 20) \right].
$$

First, compute the sum inside:

$$
9 + 17 + 20 = 46.
$$

Then multiply by 2:

$$
2 \times 46 = 92.
$$

Add the endpoints:

$$
0 + 26 = 26.
$$

So the approximation becomes

$$
I \approx 1 \times (26 + 92) = 118.
$$

Thus, the approximate total distance traveled is

$$
d \approx 118 \text{ feet}.
$$
The approximate total distance traveled is 118 feet.
