Comparing Rates of Speed: Proportional Relationships Between Distance and Time

This video tutorial teaches how to compare rates of speed by analyzing the proportional relationship between distance and time. It explains the concept of unit rate, which is calculated by dividing total distance by total time, and how it helps determine who is traveling the fastest. The tutorial uses examples to illustrate these concepts and shows how to graph the data to visualize constant rates. The person with the highest unit rate is the fastest, and graphs with steeper slopes represent higher speeds.

Explain the relationship between distance, time, and unit rate.
