Question

If a car can travel 27 4/5 miles on a gallon of gas, how far will it travel on 1/2 gallons of gas

Answer 1

`\sf \text{Distance traveled on a gallon of gas = } 13 (9)/(10) \ miles`

Explanation:

When the quantity of fuel increase, it covers more distance and when the quantity of fuel decrease, the vehicle travels less distance.

To find the distance travelled, multiply the distance by the fuel consumed.

`\sf \text{Distance traveled on a gallon of gas = } \ 27(4)/(5) \ miles`

`\sf = (139)/(5)`

`\sf \text{Distance traveled on $(1)/(2)$ gallon of gas = } \ (139)/(5)*(1)/(2)`

`\sf = (139)/(10)\\\\\\ = 13(9)/(10) \ miles`

Answer:

`\sf \text{Distance traveled on a gallon of gas = } 13 (9)/(10) \ miles`
