It’s Super Race Day! Two-person teams will compete to win different events and the right to be crowned Super Race Champions. Fathers and sons, mothers and daughter, siblings, and best friends compete in events such as Scooter Rendezvous, Flyer Scramble, Mixture Madness, and Canoe Races.

 

In the last lesson you learned how to solve rational equations. In this lesson you will learn how to use rational equations to solve practical problems. These problems will centre on the events of Super Race Day.

 

Outcomes

 

At the end of this lesson you will be able to

  • solve problems by modelling a situation using a rational equation

Lesson Questions

 

You will investigate the following questions:

  • What types of problems related to co-operative and competitive games can be solved by rational equations?

  • How can real-world problems be modelled with rational expressions and rational equations?
