Final answer:
The unit of a caterpillar's speed with the given units would be centimeters per minute (cm/min). The data would be graphed with Time (min) on the x-axis and Distance (cm) on the y-axis, each carefully scaled and labeled with units.
Step-by-step explanation:
To determine the unit of a caterpillar's speed when measuring distance in centimeters (cm) and the time it takes to travel that distance in minutes (min), we first consider the formula for speed, which is distance divided by time. Therefore, the unit for the caterpillar's speed would be centimeters per minute (cm/min).
When graphing this data, we would place Time (min) on the x-axis and Distance (cm) on the y-axis. The axes should be clearly labeled, including the units of measurement. For the x-axis, we may choose a scale that allows for increments that match the regular intervals at which time was recorded – for instance, every 10 minutes. Similarly, the scale for the y-axis should be chosen to cover the entire range of distances traveled by the caterpillar, potentially with increments that facilitate easy reading, such as every 5 or 10 centimeters.
