Read each question carefully and solve for the missing variable. Show your work where applicable. Remember the formulas: Speed = Distance/Time, Distance = Speed × Time, Time = Distance/Speed.

1. A car travels a distance of 300 kilometers in 5 hours. What is its average speed?

4. To calculate speed, you need to divide the   by the  .

5. Which of the following units is commonly used for speed?

6. If you increase the distance traveled while keeping the time constant, your speed will decrease.

7. The graph below shows the distance traveled by a cyclist over a period of time. Use the graph to answer the questions.
