Miles per hour is calculated by knowing how long an object has been moving and how many miles it has covered in that span. Divide the number of miles traveled by the hours spent traveling to calculate miles per hour.

You will learn:How to calculate the velocity from a distance time graph, how to calculate acceleration from a velocity time graph, and how to calculate distance covered.

The video eaches you how to solve typical linear word problems (story problems or applied problems). In this segment, the instructor briefly explains the rate/time/distance formula while using specific examples to solve. Clear, concise, and easy to u...nderstand.
[NOTE: This video is only a 12-minute portion of the full 3-hour lesson. Please visit instructor's website to purchase complete version.][more]

You will learn: How to calculate the velocity from a distance time graph, How to calculate acceleration from a velocity time graph, and how to calculate distance covered.

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.[more]

For high school students. Algebra Word Problem: Distance Rate and Time using two jets. Seasoned math instructor demonstates on white board. Uses colored markers for clarification.

From nctm.org, produced by National Council of Teachers of Mathematics

This manipulative is from the National Council of Teachers of Mathematics website. Some vehicles fly down the highway, while others are dirt-track specialists. This activity allows you to explore the relationships between distance, rate, and time. ...Can you identify the best path for a vehicle? Try to predict what will happen if you set on‑road or off‑road performance measures.
Note: There are more instructions by the manipulative.[more]

Students learn that a proportion is an equation that states that two ratios are equal. Students then learn the properties of proportion, and are asked to solve for x in given proportions, and to solve word problems involving proportions. Instructor u...ses a white board for instruction. For sixth-grade and up.[more]
