The recommended speed on a scenic road is  mph. Driving too fast is a hazard, but so is driving too slowly. Safe speeds s may be described by the inequality ≤ 10.  

  1. Find a list of at least safe speeds.

    What values can you substitute for s that would make this inequality true? Remember, there can be many different answers.

    One possible answer is mph.

  2. Determine how to show the entire set of possible values (solutions) for s by graphing them on a number line.

    Use your list from part (a). You will need to determine the fastest and the slowest safe speeds.
