  1. A car travels 50 miles per hour for 2 hours and 40 miles per hour for 1 hour. Homework Help ✎

    1. Sketch a graph of velocity vs. time. Label the axes with units.

    2. Fill out the table below for the distance vs. time.

    3. Graph the function of distance vs. time. Label the axes with units.No Calculator icon

Plot time on the x-axis and velocity on the y-axis.

Notice that velocity is constant for the first two hours, and then has a different constant value for the remaining hour. What do constants look like on a graph?

Consider the Freeway Fatalities problem 1-1... Recall that distance information can be found by calculating the area under a velocity graph.

Graph the data in the table and connect.
Note that distance is measured in miles and time is measured in hours.
