A train is traveling at a constant speed and goes kilometers in 6 minutes. At that rate:

1. How far does the train go in 1 minute?

   

2. How far does the train go in 100 minutes?
3. How long does it take the train to travel 100 kilometers?
4. Create a representation of your choice that shows the relationship between the elapsed time and distance traveled for this train.

Lin ran miles in of an hour. Noah ran miles in of an hour.

Who ran faster, Noah or Lin? Explain or show your reasoning.

In real life, the Mona Lisa measures feet by feet. A company that makes office supplies wants to print a scaled copy of the Mona Lisa on the cover of a notebook that measures 11 inches by 9 inches.

1. What size should they use for the scaled copy of the Mona Lisa on the notebook cover?

2. What is the scale factor from the real painting to its copy on the notebook cover?

3. Discuss your thinking with your partner. Did you use the same scale factor? If not, is one more reasonable than the other?
