Explain what each line segment in the graph represents.
Are they traveling at the same speed all throughout the trip?
A portion of the trip at a specific speed.
About how many miles is it from Vacaville to Los Angeles? How do you know?
Which axis represents miles?
Using the graph shown above, sketch a graph that would represent their speed while traveling. Take your time to think this through carefully and be sure to label the axes.
To find the speed for a portion of the trip, divide the number of miles traveled in that portion by the number of hours it took to travel that portion.
Graph shown below - a speed of approximately
mph for hour, approximately mph for the next hours, mph for hours, approximately mph for hours, and then approximately mph for the last hours; note that the step graph assumes instantaneous change of speed, which is not technically possible.
