Calculating speed and distance has many practical uses in the everyday world. People can use these calculations in sports, for example, to see how fast a baseball is thrown, when traveling, or to see the distance they traveled while driving. The formula for speed is distance divided by time. The formula for distance is speed times time.

### Speed

Determine the distance traveled. For example, a person walks half a mile to work each day.

Determine the time it takes to travel the distance. In the example, it takes the person 30 minutes.

Divide the distance by the time. In our example, 0.5 miles divided by 0.5 hours equals a speed of one mile an hour.

### Distance

Determine speed when traveling. For example, a person driving to work travels at an average speed of 30 miles per hour.

Determine the travel time. In the example, it takes the person 45 minutes or 0.75 hours.

Multiply the speed by the time to calculate the distance. In our example, 30 miles per hour times 0.75 hours equals 22.5 miles traveled.
