In preparation for the Boston Marathon, we thought that an analysis of running speeds might be appropriate.
Have you heard of The Six Million Dollar Man? He was the character in a science fiction show about an astronaut that was rebuilt, bionically, after his space ship crashed. He could run at 67 miles per hour.
This activity compares the best short and long distance record speeds as students learn the logic and mechanics of using fractional expressions for the number one to convert meters per second to kilometers per hour, etcetera.
These are two ways that you could begin this activity: (1) For fun: Play this video of The Six Million Dollar Man running. Or (2) (for a more serious opening) Play this video of Usain Bolt's 2009 World record 100-meter run in Berlin.
