Arrange It!
Lilly wants to visit her friend. The trip usually takes about 30 minutes if Lilly walks, but today she decides to take her bike instead.
In this activity, you will see the distance–time graph of Lilly's trip, which includes two lines. A blue line shows her usual trip on foot, and a red line is the actual graph of her trip on a bike. You will now drag labels onto the red line to show what happened during Lilly's bike trip and compare it to her usual trip on foot. Click below to begin the activity. Your teacher will review the answers with you.
Then, before moving on to the final assignment, you may want to watch this lesson's videos again or reread Ahead or Behind?
