Math Problem Statement
Solution
The problem involves calculating the fuel efficiency of two cars (blue and red) in terms of miles per gallon, based on their given fuel consumption and distance traveled.
Blue Car:
- The blue car travels miles on gallons of gasoline.
To find the unit rate (miles per gallon), we divide the distance by the amount of fuel consumed:
Red Car:
- The red car travels miles on gallons of gasoline. First, convert the mixed number to an improper fraction:
Now, divide this distance by the fuel consumed:
Conclusion:
- The blue car has a fuel efficiency of 2 miles per gallon.
- The red car has a fuel efficiency of 26 miles per gallon.
Thus, the red car can travel a greater distance on 1 gallon of gasoline.
