3. Describe the measurements necessary to find the average speed of a high school track athlete. 4. Determine the unit of a caterpillar's speed if you measure the distance in centimeters (cm) and the time it takes to travel that distance in minutes (min). How would you graph the data?

## Step 1: Identify Necessary Measurements for Average Speed### To find the average speed of a high school track athlete, you need to measure two key quantities: the total distance covered and the total time taken. The average speed is calculated using the formula: These measurements can be obtained by timing the athlete over a known distance, such as a lap around the track.## Step 2: Determine Unit of Caterpillar's Speed### When measuring the distance in centimeters (cm) and the time in minutes (min), the unit of speed will be centimeters per minute (cm/min). This is because speed is defined as the distance traveled divided by the time taken, so the units of measurement for distance and time directly determine the unit of speed.## Step 3: Graphing the Data### To graph the data of a caterpillar's speed, plot the distance on the y-axis and the time on the x-axis. Each point on the graph represents the distance traveled at a specific time. The slope of the line connecting these points indicates the speed of the caterpillar. A steeper slope corresponds to a higher speed.
