I have completed a problem and would like you to check it and see if I got it right.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The velocity graph of a car accelerating from rest to a speed of 120 km/h over a period of 30 seconds is shown. Estimate the distance traveled during this period

Here is the graph, where a=40 http://www.webassign.net/scalcet/5-1-016alt.gif

3. The attempt at a solution

You will see a print screen of my work. Did I do correctly that I put together a lower and upper estimates and divided the sum by 2 in order to estimate the distance traveled? I believe I made a mistake.
