Question

Demarco has two cars: an SUV and a compact car. the fuel efficiency of the compact car is 1 7/12 times better than the SUV. If the SUV gets 16 miles per gallon, find the fuel efficiency of the compact car.

Answer 1

The fuel efficiency of the compact car is 25.33 miles/gallon.

Explanation:

The fuel efficiency of the an SUV = x = 16 miles/gallons

The fuel efficiency of the a compact care= y

Given:
`y=1(7)/(12)* x`

`=y=(19)/(12)* x`

`y=(19)/(12)* 16 miles/gallon=25.33 miles/gallons`

The fuel efficiency of the compact car is 25.33 miles/gallon.

Answer 2

Fuel efficiency of compact car =
`(17)/(12)` * Fuel efficiency of the SUV

Fuel efficiency of SUV = . 16 miles per gallon

⇒ Fuel efficiency of compact car =
`(17)/(12)` * 16

⇒ Fuel efficiency of compact car = 22.67 miles per gallon
