Answer
The approximate total distance traveled is 118 feet.
Solution
We are given data for
and
and need to approximate the total distance traveled from 0 to 8 seconds using the trapezoidal rule with
subintervals.
Since the interval is from 0 to 8 seconds, the width of each subinterval is
The trapezoidal rule formula for approximating the integral is
where
is the velocity at time
.
We choose the points corresponding to
seconds. From the table:
- At
: - At
: - At
: - At
: - At
:
Substitute these values in the formula:
First, compute the sum inside:
Then multiply by 2:
Add the endpoints:
So the approximation becomes
Thus, the approximate total distance traveled is

To approximate the total distance traveled using the trapezoidal rule with
, we first need to divide the interval from
to
seconds into four segments. The points will be at
.
The velocity at these time points is:
Now we can apply the trapezoidal rule:
where
.
Substituting the values, we have:
Calculating further:
Thus, the approximation for the total distance traveled from 0 to 8 seconds is
