Lessons 2: Quartertime!
In most cases, as more variables are added to a problem, the more complex the solution becomes. In Lesson 1 you solved a problem with three fueling stations. Now, can you step up and decide where to place a new fueling station that least impacts four existing stations? Have a gas!
Doing the science
- Start the Fueling Station Simulation by clicking on the "Sim" tab.
- Click the "New Problem (4)" button located at the top of the screen.
- Note and record in Table 1 the letter and location of each current fueling station.
- Follow the on-screen instructions to place each current station in its appropriate location. Do this by dragging the letter icon of the station to its location on the gridded street map.
- After all four stations are properly located, click the "Please Select One" drop down menu and choose "Segment." Again, follow the on-screen directions to draw line segments. Click on the "Make It" button to actually draw the segment. If you need help, click the "Terms" button at the bottom left-hand corner of the screen to find out more about segments.
- After all four stations have been connect via four line segments, click the "Please Select One" drop down menu and choose "Midpoint." Again, follow the on-screen directions to draw the four lines’ midpoints.
- After you create the midpoints for each of the four segments, click the "Please Select One" drop down menu and choose "Perpendicular Bisector." Again, follow the on-screen directions to draw the four lines’ perpendicular bisectors.
- Use your drawing to determine the best location for the new fueling station. Write the location of the new fueling station in Table 1.
