Question

calculate the gas mileage of a car that drives 283 miles on 12.3 gallons of gas. Round to the nearest tenth of a mile/gallon

Answer 1

I just did 283 divided by 12.3 which is 23

Answer 2

we know that

Unit Rate is the ratio of two measurements in which the second term is
`1`

by proportion

Find the number of miles a car drives with a gallon of gasoline

`(283)/(12.3) (miles)/(gallons) =(x)/(1) (miles)/(gallon)\\ \\12.3*x=283\\ \\x=283/12.3\\ \\x=23\ miles`

therefore

the unit rate is equal to
`23(miles)/(gallon)`

The answer is

`23(miles)/(gallon)`
