Description: Sal is given a table of values that represents a person walking to work, and is asked to determine which verbal description represents someone starting at the same distance from work. Created by Sal Khan. Charles and Tammy live the same distance from work, and they started walking to work at the same time. Then another 50 seconds goes by, and now he's 760 meters from work. Another 50 seconds goes by, and he's 690 meters from work, which makes sense.
