Calculating Fuel Efficiency and Rates

The video tutorial explains how to solve two problems using unit rates. First, it shows how to calculate the distance a car can travel on 38 gallons of gas by determining the unit rate of miles per gallon. Then, it demonstrates how to find the number of gallons needed to drive 1,200 miles using the unit rate of gallons per mile. The tutorial emphasizes converting given information into rates and calculating unit rates to solve practical problems.
