The world is full of change. It can be sunny and dry one minute and rainy the next. Changes lead to questions like these:

  • How quickly?
  • How long?
  • How do these changes compare?

In this section you used proportional reasoning and unit analysis to solve slope and rate problems. You saw how tables can help you set up proportions and noted that there is a connection between the slope of a graph and unit rates. You were able to give answers in both the imperial and SI measurement systems.

 

In the Module 3 Project: Luge Track Comparison, you looked at slopes of tracks and the consequences of the slopes. You compared the slopes of Canada’s two Olympic luge tracks with the safety requirements for tracks. You also compared the slopes of the two tracks and the speeds athletes reached on the tracks.
