For each graph, write an explanation of the situation (in complete sentences) that gives the important information contained in the graph. 2For each graph, decide when the velocity is increasing and when the velocity is decreasing. 3. Try to give a formula for the velocity in terms of time 4. Decide whether you think the car could behuve like the model. Explain your reasons. 5. Sketch the graph of the distance the car has traveled since r-Q, versus time 6. Try to find a formula for distance in terms of time. 7. For each graph, decide when the car is furthest away from Dallas. Explain. 40 10 -10 I0 (hrs) (hrs) 70 70 60 50 40 mph) mph) 10 -10 (hrs) -10
