Unit Rate Problem Solving Challenge

This video tutorial covers the concept of unit rates and their application in solving real-world problems. It includes three examples: calculating the distance a jet travels at a constant speed, determining the cost of cheese slices, and finding the travel time for a ferry. The tutorial emphasizes the importance of consistent labeling and provides methods to verify solutions using unit rates and cross-multiplication.

What does 'constant speed' imply in the context of the jet's movement?

• The speed increases over time.

• The speed remains the same throughout.

• The speed decreases over time.

• The speed varies over time.
