ok i kind of winged it and got 188? is that right?

mathmale · Answer

It's so much more important to me that you understand the concepts and processes involved than you merely get an "answer."

If you're interested, I'll discuss what to do to estimate the distance traveled.

You're given a table of values which represent different velocities as different times.  Because distance = rate * time, finding the area under the velocity "curve" will give you the approx distance you want.  Have you done this kind of problem before?

anonymous · Answer

no it was my first time with this

mathmale · Answer

You have several methods to choose from:
1.  trapezoidal rule for estimating areas under a curve over an interval
2.  Simpson's rule
3.  midpoint rule

there are others, but these are enough for now.  Which are you familiar with?

anonymous · Answer

trapezoidal is the one im most familiar with but we're starting to learn simpsons rule

mathmale · Answer

The trap. rule is a bit easier (but not much easier), if a little less accurate than Simpson's Rule.  Have you actually done any trap. rule problems before?

If not, have you an example from class or online notes?

anonymous · Answer

yeah i have some notes on it. ive done a few problems with that rule.

mathmale · Answer

Great.  What info need you from me to help you get started with this particulzar problem?

mathmale · Answer

Can you explain in your own words what this formula is for?$$\Delta x=\frac{ b-a }{ n }$$ and what a, b and n represent?  You'll need this formula.

anonymous · Answer

how do i get started finding the the function? i have to go but ill be on later.

mathmale · Answer

All right.  When you return, please answer my questions.  See you later!
