This is not directly about metric, in fact it is about miles per hour. But it
is a sad commentary on math education in the United States.

What is odd is the woman isn't an idiot, she comes surprisingly close with her
roundabout, but naive solution. She simply doesn't relate to the concept. The
question is how long does it take to go 80 miles at 80 mph.

one system well.
