​Study Tip: You learned about ratios, rates and unit rates in previous classes

Find unit rates with fractions​

As a whole class, let's analyze the given problem​

Three friends ​are training for a one mile race. Their rates are shown in the table.

How long will it take Sasha to run 1 mile​ at her current rate? What method do you think we can use to find the answer? Share with the class

​

Now that you have thought about possible ways to find the asnwer, ​

How could you use a bar diagram to find the solution?​

How can you use scaling to find Sasha's unit rate?​

​

​It is time to work with your groups to find the solution

With your groups ​

​Work it out with a partner
