Technology is a tool that can be helpful as part of a problem solving strategy. Models that were made by hand in the past are now made on computers with virtual machines called applets. Today we are going to use technology to help us solve a problem: what are the best gears to use on a bicycle when I want to get to a friends house as fast as possible. The link on the right is an applet that will help us answer the question. Read the instruction, play the game and then answer the questions below.
1. If my friends house is in the city two miles away on flat ground, which two gears would get me there as fast as possible?
2. Why would I ever want to use the two slowest gears?
3. If you could only choose one pair of gears which would you choose and why?
4. How many possible choices would you have on the bike used in the applet?
