A family has two cars. The first car has a fuel efficiency of miles per gallon of gas and the second has a fuel efficiency of miles per gallon of gas. During one particular week, the two cars went a combined total of miles, for a total gas consumption of gallons. How many gallons were consumed by each of the two cars that week?
Answer provided by our tutors
gallons were consumed by each of the two cars that week are 40 and 15

then (55-Y)x 20 =1300- X
Y x 25 = X
so Y = 40, X = 1000
