Describe the relationship between distance and travel time.

• Positive
• Linear
• Strong

How would the relationship change if travel time was instead measured in hours, and distance was instead measured in kilometers?

Stay the same.

Correlation between distance (in miles) and travel time (in minutes) is r = 0.636. What is the correlation between distance (in kilometers) and travel time (in hours)?

Remains at r = 0.636.
