  1. PA U2C1A6 Remember speed is a rate!

  2. PLEASE, flip to the back of your handout to take some notes! d = s x t d s = d  t s t t = d  s

  3. d s t

  4. s  d  t d  s  t t  d  s d s t

  5. 2. What is the speed of the toy car mentioned in the problem on the previous page?Show your work. S = dt S = 142 = 7 m/s

  6. 3. If a car travels with a constant speed of 80 km/h for 0.6 h, how far does it travel? Show your work. d = st d = 80km/h  0.6h d = 48 km

  7. 4. If a jogger moves at a constant speed of 3 m/s along a sidewalk that is 99 m long, howlong does it take the jogger to run the length of the sidewalk? Showyourwork.

  8. 5.A jet travels with a constant speed of 600 mi./h between two cities separated by 4500 mi.How long does the flight take? t = 4500 mi 600 mi/h

  9. 6. Rachel walks to a movie theatre to see a film with her friend Ali. Moving at a constantspeed of 6 km/h, Rachel takes 0.75 h (45 min) to walk from her home to the theatre. Howfar away is the theatre from Rachel’s home? Distance = Speed  Time d = 6 km/h  0.75 h

  10. 7. What is the slope of the line plotted in the graph below?

  11. 8. Which car has the highest speed? Remember the connection between speed and slope!

  12. 9. Although all four cars are pointed to the right (east), one car is moving left (west) in reverse gear. Which car is moving in reverse?

  13. 10. Which car is not moving?

  14. 11. Which of the following graphs shows a linear relationship between x and y?
