Students learn how to solve complex problems involving speed, distance and time.

Later, as learning progresses they model multiple parts of a journey algebraically to set up and solve linear equations.

**Differentiated Learning Objectives**

- All students should be able to calculate speed using the S=D/T triangle.
- Most students should be able to model a multiple part journey using a time line
- Some students should be able to model a multiple part journey algebraically.
