Question

Mrs.Allans car uses 8 gallons of gas for a 224-mile trip. Mrs.Owens car uses 6 gallons of gas for a 210-mile trip.

PartA: What are the unit rates for each cars gas usage?
PartB: Whose car has better gas mileage?

PartC: At these rates, how many gallons of gas would each car use if both cars traveled 560 miles? Explain

Answer what you can please. It is appreciated

Answer 1

A.Rate of Mrs. Allan's car=28 mile/gallon

Rate of Mrs. Owen's car=35 mile/gallon

B.Mrs. Owen's car

C.Mrs.Allen's car used gas for 560 miles=20 gallons

Mrs.Owen's car used gas for 560 miles=16 gallons

Explanation:

We are given that

Mrs. Allan's car uses 8 gallons of gas for 224 mile tripe.

Mrs. Owens car uses 6 gallons of a gas for 210 mile tripe.

A.Rate=
`(Distance\;traveled)/(Gas;used)`

Rate of Mrs. Allan's car=
`(224)/(8)=<strong>28 </strong>mile/gallon`

Rate of Mrs. Owen's car=
`(210)/(6)=<strong>35</strong> mile/gallon`

B.Mrs.Allan's car travel in 1 gallon of gas =28 miles

Mrs. Owen' s car travel in one gallon of gas=35 miles

Therefore, Mrs. Owen's car travel large distance in one gallon of gas.Hence, it is better.

C.If distance traveled by the cars=560 miles

Mrs. Allen's car used gas for 28 mile=1 gallon

Mrs. Allen's car used gas for 1 mile=
`(1)/(28)`

Mrs.Allen's car used gas for 560 mile=
`(560)/(28)=20 gallons`

Mrs.Allen's car used gas for 560 miles=20 gallons

Mrs.Owen's car used gas for 35 miles=1 gallon

Mrs. Owen's car used gas for 1 mile=
`(1)/(35)`

Mrs. Owen's car used gas for 560 miles=
`(560)/(35)=16 gallons`

Mrs.Owen's car used gas for 560 miles=16 gallons

Answer 2

A. Mileage is read in Miles per gallons

B.Hence ownens car has a better mileage

C. Allans CAr : 20 gallons

Owens car : 16 Gallons

Explanation:

Allans Car

Distance traveled = 224 miles

Fuel consumed = 8 gallons

Distance covered in 1 gallon =
`(224)/(8)` = 28

Hence mileage is 28 miles per gallon

Owens Car

Distance traveled = 210 miles

Fuel consumed = 6 gallons

Distance covered in 1 gallon =
`(210)/(6)` = 35

Hence mileage is 35 miles per gallon

Hence ownens car has a better mileage

If the Distance traveled by both car is 560 miles

Allans car

Fuel consumed =
`(560)/(28)` = 20 gallons

Owens car

Fuel consumed =
`(560)/(35)` = 16 gallons
