Make your foldable, after finishing Roadrunner Challenge Fold your paper in half like a hotdog and then into 3 sections. Label each section like the example above. SPEED What do you need to know to calculate this horse’s average speed? Definition Speed is the distance traveled by an object divided by the time taken to travel that distance. average speed= total distance total time Let’s Solve a Problem together! An athlete swims a distance from one end of a 50m pool to the other end in a time of 25s. What is the athlete’s average speed? - Step one: Write the equation for average speed. - speed= total distance total time - Step two: Replace the total distance and total time with the values given, and solve. - speed= 50m 25s =2 m/s This is how your foldable will begin to look. Kira jogs to a store 72 m away in a time of 36 s. What is Kira’s average speed? Speed=distance time =72m 36s =2m/s If you travel 7.5 km and walk for 1.5 h, what is your average speed? Speed = distance time = 7.5km 1.5h = 5 km/h An airplane traveling from San Francisco to Chicago travels 1260 km in 3.5 h. What is the airplane’s average speed? Speed = distance time = 1260 km 3.5 h = 360 km/h Velocity Velocity describes both speed and direction. Example: If you say that an airplane’s velocity is 600km/h, you would not be correct. But you could say the plane’s velocity is 600km/h south.
