## GPS-Finding shortest time and shortest distance

This is an open ended graphing problem that has students think about travel form one end of town to the other. They are presented with the problem you have two routes to choose from. You need to find the one that is the shortest distance and which one is the shortest time. Then they are introduced to graphing each route and using linear segments (piecewise functions). This opens up a whole set of questions about slope (rate of change), distance, midpoint, average, etc. Standards are included in the lesson. It is important to point out that I have my students work in groups to pull together a list of thing (data) they need to solve the problem. I then supply them with two routes. #VegasPBS-Math410
