Instructions
Read the following questions carefully and answer them to the best of your ability. Use the speed graphs provided to help you interpret the data.
Part 1: Speed Graphs
Study the speed graphs below and then answer the questions.
Graph 1: A car's speed over a 10-minute trip
Time (minutes): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Speed (km/h): 0, 20, 40, 60, 80, 60, 40, 20, 0, 0, 0
Graph 2: A cyclist's speed during a 10-minute ride
Time (minutes): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Speed (km/h): 0, 10, 15, 20, 25, 30, 25, 20, 15, 10, 0
Questions
1. What was the maximum speed of the car during its trip?
2. At what minute did the car reach its maximum speed?
3. Describe the pattern of speed for the car. Use the space below to provide your answer.
4. What was the maximum speed of the cyclist during the ride?
5. Compare the speed patterns of the car and the cyclist. How do they differ?
6. Why do you think the car's speed decreased after reaching its maximum?
7. If the car and the cyclist continued on their paths, predict what might happen next for both.
Part 2: Reflection
8. How does understanding speed graphs help in real-life situations such as driving?
