Question

Order the cars based on how far they drive on 1 gallon of gas. Place the car that travels

farthest on top.

0.2 gallons used for 7 miles

0.5 gallons used for 12 miles

0.9 gallons used for 25 miles

Answer 1

Explanation:

First car.

0.2 gallons used for 7 miles.

Distance drive on 1 gallon of gas
`=(7)/(0.2)=35\ \text{miles}`

Second car.

0.5 gallons used for 12 miles.

Distance drive on 1 gallon of gas
`=(12)/(0.5)=24\ \text{miles}`

Third car.

0.9 gallons used for 25 miles.

Distance drive on 1 gallon of gas
`=(25)/(0.9)=27.8\ \text{miles}`

So, the first car traveled fast while the second car traveled least. Hence, the sequence is first car > third car > second car.
