A black rectangle and the pause button will take you 70% of the way.
Where do you put the black rectangle? What question does that provoke?
BTW: I would put a black rectangle above Rich Eisen's speed and ask the students to guess at his speed. Then they're converting from yards per second to miles per hour and you have a nice conversation about good time intervals for that calculation. (If you time him over the entire forty-yard dash, your estimate will be well below his top speed.)
Where do you press pause? What question does that provoke?
BTW: I would press pause on the clip where Eisen gets a head start on Jacoby and ask them how long it will take Jacoby to catch up to Eisen. Which is a nice enough way to introduce systems of equations.
