A family had two cars. The first car fuel efficiency of 20 miles per gallon of gas and the second car has a fuel efficiency of 40 miles per gallon of gas. During one particular week the two cars went a combined Total of 1100 miles for a total gas consumption of 40 gallons how many gallons were consumed by each of the two cars that week?

Gas consumed by first car is 25 gallons

Gas consumed by second car is 15 gallons

Step-by-step explanation:

First car rate = 20 miles / gallon

Number of gallons = x

Distance = 20x miles

Second car rate = 40 miles / gallon

Number of gallons = (40 - x)

Distance = 40 (40 - x) miles

20x + 40(40 - x) = 1100

20x + 1600 - 40x = 1100

20x - 40x = 1100 - 1600

- 20x = -500

multiply through by -1

20x = 500

x = 500 / 20

x = 25

Gas consumed by first car = 25 gallons

Gas consumed by second car = 40 - 25

                                                  = 15 gallons

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
