While entering the Garden State Parkway, you take a ticket at one toll
plaza and exit at the next one a known distance away. The ticket is
stamped by a time clock as you take it at the entrance point. At the exit
point can the toll collector determine if you ever exceeded the speed
limit for the Parkway? Explain.

I have a Kia Soul, which also displays mpg. Very cool! Here's another nice
problem, which can be adapted to any highway:

I get interesting answers on this one. It also leads to good discussions
about, you guessed it, average speed!
