The graph below shows distances traveled by Car A and Car B. Car A is represented by the line containing point A, and Car B is represented by the line containing point B. Use the graph to answer the following questions. Homework Help ✎
Which car is traveling faster? How can you tell?
Find the coordinates of point A and point B.
How fast did Car A travel (in miles per hour)? How fast did Car B travel?
Does the distance Car A has traveled vary directly with the time? Why or why not?
The faster car has a steeper line.
Car A is traveling faster.
A: (2, 120)
B: (4, 120)
Use the same process for Car B as you did for Car A.
Car A: 60 miles per hour
Car B: 30 miles per hour
Yes because the distance = constant · time.
