Same Speed

Students use the Student Workbook to:

- Read the problem

- Do the experiment

- Do the math

FlyBy MathTM

Understand the Problem

- Speed of each plane = 1/2 foot per second

16 ft

20 ft

- Will the planes meet at the intersection?

- If not, how far apart will they be when the first plane arrives?

The Physical Experiment

- Students act as Pilots, Controllers, and NASA Scientists.

- Students lay out two jet routes.

- Pilots step down the routes.

- Students measure and record time and separation distance.

FlyBy MathTM

Six Math Methods

- Count feet and seconds

- Draw and stack blocks

- Plot points on two vertical lines

- Plot points on a grid

- Derive & use the distance-rate-time formula

- Graph two linear equations

What happens to the planes where the lines intersect?

Distance from route start

- In each panel, we can change speed & starting position.
- A change in one panel changes the other two panels.
- Helps students link the math to the real world.

- When the lines cross on the graph, do the planes collide?
- We can use the simulator to answer the question.

- On the graph, the lines intersect at (30, 15).
- At 30 sec, each plane is 15 ft from its jet route start.
- Note: the planes are on 2 routes that intersect at 20 ft.

- On the graph, the lines again intersect at (30, 15).
- At 30 sec, each plane is again 15 ft from the jet route start.
- Note: the planes are flying on the same route.

- For 2 planes on 2 routes, configure the graphto represent a collision.
- Hint: Where is the only place on the routes a collision can occur?

At the intersection at 20 feet.
