# I'm not speeding, officer!

Calculus Level 2

A motorist is driving down the freeway that has a speed limit of $60$ MPH. The police car he passes at $10\text{:}30$ AM records him as going $60$ MPH, so he isn't pulled over. Two hours and $156$ miles later, he passes another police car, again registering as traveling at $60$ MPH, so once again he is not pulled over. At some point during the trip, was he speeding? If so, you know this due to which theorem?
