Students learn to solve introductory "motion" word problems -- for example, cars traveling in opposite directions, bikers traveling toward each other, or one plane overtaking another. Students should first draw a diagram to represent the relationship between the distances involved in the problem, then set up a chart based on the formula rate times time = distance. The chart is then used to set up the equation. The instructor uses a white board for demonstration and this video is suitable for high school students.
