using the graph please answers questions 2-7

2. Using the graph, what is the distance traveled at 4.5 hours? ________ miles

3. Using the graph, how long does it take the car to travel 60 miles? _________ hours

4. The slope of the graph is the speed and is determined by using two points (x₁, y₁ and x₂, y₂) on the best-fit line.

Slope = y₂ - y₁ / x₂ - x₁

Label the points on the graph with a that you used to determine the slope. What is the speed of the car? Why can't you use the actual data points to determine speed?

5. Using the graph, how many kilometers would the car travel in 200 minutes?

6. Since distance equals speed times time (d = s t), how far would the car have traveled in 24 hours?

7. If the car started to slow down at the end of its journey, would this influence the graph? Use the graph to show this relationship, if it exists.
