Question 1124176: A family has two cars. During one particular week,the first car consumed 25 gallons of gas and the second consumed 40 gallons of gas. The two cars drove a combine total of 1875 miles, and the sum of their fuel efficiencies was 60 miles per gallon. What were the fuel efficiencies of each of the cars that week? Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website! Fuel efficiency is a separate constant for each car.
MILES per GALLON is the unit for fuel efficiency in the example.
, fuel efficincy, distance, volume
You could use two variables, but just one variable is possible and the work may be easier.
FUEL EFFICIENCY VOLUME DISTANCE
firstcar x 25 25x
secondcar 60-x 40 40(60-x)
sum 60 1875
