For mathematicians who are soon to learn how to drive, this is an especially beneficial lesson on inverse relationships! Andrew Vander Heuvel explains how increasing the speed of your car does not save much on total drive time. Rather than look at the number of miles covered in an hour, think about how much time it takes to cover a mile. The math needed to compute the amount is not explained, so after the video, have your class develop the process for calculating seconds per mile.
