Aja and Emilie were riding their skateboards. They knew that they could ride miles in 20 minutes.

  1. How far can the girls ride in minutes?

    Set up a proportion.


  2. If represents the distance in miles and represents the time in minutes, write an equation to represent the distance traveled for any time.

    You can also use a proportion for this problem.

    Multiply both sides by to simplify the equation.
