  • Instructions

    Create your course assignments by selecting questions from our bank of end-of-section exercises, as well as enhanced interactive examples with videos.

    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.

    Watch It - videos of worked examples

    Master It - tutorials

    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.

    In this assignment we present several textbook question types found in Algebra: Introductory and Intermediate: An Applied Approach 6/e by Richard Aufmann and Joanne S. Lockwood published by Brooks/Cole. This textbook also includes Expanded Problem (EP) questions, which are expanded versions of existing questions that include intermediary steps to guide the student to the final answer. 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.

    Click here for a list of all of the questions coded in WebAssign. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.

  • 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?
    Correct: Your answer is correct. Your value is acceptable. mi
    How long, in hours, does it take you to travel this path from beginning to end?
    Correct: Your answer is correct. Your value is acceptable. hr
  • Part 2

    Use the values you entered in part 1 to determine the answer in this part.
    Use the equation
    d = rt
    to determine your rate of travel, in miles per hour, on this path. (Round your answer to the nearest tenth.)
    Correct: Your answer is correct. mph
  • Part 3

    Continue investigating this situation.
    Use the rate you found in part 2 and the equation
    d = rt
    to determine how long it would take you, in hours, to travel each of the trails below. (Round your answers to the nearest tenth.)
    Trail Name Distance Time (in hours)
    Matadero Creek Trail 1.5 miles Correct: Your answer is correct. hr
    WestCliff Drive Trail 3.4 miles Correct: Your answer is correct. hr
    Sabercat Creek Trail 11.2 miles Correct: Your answer is correct. hr
