  • Instructions

    Create your course assignments by selecting questions from our bank of end-of-section exercises.

    Students can view and hear additional instruction through the 2-5 minute Watch It links. Students will also find helpful links to online excerpts from their textbook, tutorials, and videos.

    Every problem includes a link to the appropriate section of a complete interactive eBook, (also available through a dynamic table of contents from the student's WebAssign homepage), allowing students to highlight and take notes as they read.

    This book also includes a Personal Study Plan (PSP). Once PSP is enabled for your course, your students can use chapter and section assessments to gauge their mastery of the material and generate individualized study plans that include various online, interactive multimedia resources. Also included are Responsive Questions (RQ), which personalize the learning experience for your students by asking them to use their own real data, which provides the variables they will use to answer each question part.

  • Part 1

    How can I predict how long it will take me to travel a nature trail?
    Use some information about a path or trail that you have previously traveled to predict your rate of travel. Recall that distance traveled is equal to the product of the rate of travel and the time:
    d = rt.
    The values you enter in this part will be used to make later calculations.
    Consider a path or trail that you have traveled before.
    How long is this path in miles?
    mi
    How long, in hours, does it take you to travel this path from beginning to end?
    hr
