The Coast Starlight Amtrak train runs from Seattle to Los Angeles. The scatterplot below displays the distance between each stop (in miles) and the amount of time it takes to travel from one stop to another (in minutes). Describe the relationship between distance and travel time. Answer How would the relationship change if travel time was instead measured in hours, and distance was instead measured in kilometers? Answer Correlation between travel time (in miles) and distance (in minutes) is r=0.636.r=0.636. What is the correlation between travel time (in kilometers) and distance (in hours)?
