This applet allows you to vary the gear ratio of a bike in order to alter the distance that it will travel. The distance traveled by a half-pedal is determined by the ratio of gears. Vary the gear ratio of a bike in various scenarios in order to capture five flags on a given course! Can you complete all of the courses?
1. How many different gear ratios are possible? How do you know?
2. Determine the distance that the bike will travel three different gear ratios.
3. Use the information you have gathered so far to play Free Ride. What do you notice?
4. Develop a table or spreadsheet that will help you play and win any route of Choose Route or Random Route.
