Solve a Real World Unit Rate Problem

The video tutorial explains how to solve a real-world unit rate problem involving Ethan's car trip. Ethan's car travels 30 miles per gallon, and gasoline costs $4 per gallon. The tutorial demonstrates calculating the number of gallons used for a 180-mile trip using the cross-product property, resulting in 6 gallons. It then calculates the total cost of gasoline for the trip, which is $24.
