9-9.

A few years ago, Carlos was driving on the New Jersey Turnpike (a toll road that collects money every few miles). He was presented with a speeding ticket as he reached the last booth. Since there were no highway patrolmen or radar on the turnpike, he could not figure out how anyone knew that he had been speeding.

1. How do you suppose his speed had been determined?

$\text{ Since Distance }= \text{Rate}\cdot \text{Time}, \text{Rate} = \frac{\text{Distance}}{\text{Time}}$

2. Using your conclusion in part (a), do you think it would be possible for someone to speed on part of their turnpike trip and not get caught?

Yes, if they drove below the speed limit on another part or if they made a stop.
