#### Description:

At the end of the popular musical Les Misérables, a dejected Inspector Javert throws himself off a bridge and into the River Seine. As he falls, he sings…and sings…and sings. According to the song, he falls for a full eight seconds!In this lesson students use quadratic functions and information about how objects fall (i.e. gravity) to determine how high Javert’s bridge must have been. Then, they use linear functions to figure out how fast he was traveling when he hit the water, and whether we can believe anything that Broadway says…er, sings.
