The graph to the right represents the distance
travelled by two different cars during a 5 hour
period of time.
1) Label the lines “faster” and “slower”
2) Was the slower car travelling at a
constant speed? How do you know?
3) Calculate the speed of the slower car,
by calculating the slope value.
Slope = y2 – y1 / x2-x1
4) Based on the value you figured out in Question #3, sketch the speed versus time graph for the
slower car.
