Which is the best type of graph to model speed a roller coaster over full two minutes it takes complete ride?

A line graph is useful for visualizing how the speed of the roller coaster changes over time, as it can clearly show the acceleration, deceleration, and any changes in speed.

The x-axis of the line graph would represent time, and the y-axis would represent speed.

- Each data point on the graph would represent the speed of the roller coaster at a specific point in time.

- By connecting the data points with a line, the graph would show the overall trend of the roller coaster's speed throughout the ride.

This type of graph allows you to easily identify the highest and lowest speeds reached during the ride, and the rate at which the roller coaster accelerates and decelerates.
