  1. ESSENTIAL QUESTION How do I recognize the units of measure for distance, time and speed?

  2. DISTANCE • meters m • kilometers km • centimeters cm • millimeters mm • miles mi • inches in • feet ft

  3. TIME • seconds s • minutes min • hours hr • milliseconds ms

  4. SPEED • Since speed is • distance • divided by • time, • the units of speed are • the units of distance • divided by • the units of time

  5. SPEED • meters per second m/s • meters per hour m/hr • kilometers per hour km/hr • miles per hour mph • centimeters per min cm/min • feet per second ft/s • meters per millisecond m/ms

  6. List d= , t= , v= • A man runs 200 meters in 25 seconds. What is his average speed? • d= • t= • v=

  7. List d= , t= , v= • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m • t= 25 s • v= ___ m/s

  8. What formula should you use? • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m • t= 25 s • v= ___ m/s

  9. What formula should you use? • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s • v= ___ m/s

  10. Substitute the variables. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s • v= ___ m/s

  11. Substitute the variables. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s v = (200m) / (25s) • v= ___ m/s

  12. Solve. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s v = (200m) / (25s) • v= ___ m/s

  13. Solve. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s v = (200m) / (25s) • v= ___ m/s v = 8 ____

  14. List the units of measure. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s v = (200m) / (25s) • v= ___ m/s v = 8 ____

  15. List the units of measure. • A man runs 200 meters in 25 seconds. What is his average speed? • d= 200 m v = d / t • t= 25 s v = (200m) / (25s) • v= ___ m/s v = 8 m/s

  16. List d= , t= , v= • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= • t= • v=

  17. List d= , t= , v= • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= • t= 5 s • v= 2.5 m/s

  18. What formula should you use? • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s • v= 2.5 m/s

  19. Substitute into the formula. • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s d = (2.5 m/s)(5 s) • v= 2.5 m/s

  20. Solve. • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s d = (2.5 m/s)(5 s) • v= 2.5 m/s

  21. Solve. • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s d = (2.5 m/s)(5 s) • v= 2.5 m/s d = 12.5 ___

  22. List the units of measure. • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s d = (2.5 m/s)(5 s) • v= 2.5 m/s d = 12.5 ___

  23. List the units of measure. • A toy car travels at 2.5 m/s for 5 seconds. How far did it go? • d= d = vt • t= 5 s d = (2.5 m/s)(5 s) • v= 2.5 m/s d = 12.5 m

  24. List d= , t= , v= • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= • t= • v=

  25. List d= , t= , v= • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m • t= • v= 3 m/s

  26. Write the formula. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m • t= • v= 3 m/s

  27. Write the formula. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= • v= 3 m/s

  28. Substitute. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= • v= 3 m/s

  29. Substitute. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= = (12 m) / (3 m/s) • v= 3 m/s

  30. Solve. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= = (12 m) / (3 m/s) • v= 3 m/s

  31. Solve. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= = (12 m) / (3 m/s) • v= 3 m/s t = 4 ___

  32. Write the units of measure. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= = (12 m) / (3 m/s) • v= 3 m/s t = 4 ___

  33. Write the units of measure. • A bee flew across a 12 meter wide room at 3 m/s. How much time did this take? • d= 12 m t = d / v • t= = (12 m) / (3 m/s) • v= 3 m/s t = 4 s
