What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon of gasoline?

Respuesta :

Answer:

See below in bold.

Step-by-step explanation:

Blue car: unit rate = miles / gallons used =  36 1/2 / 1 1/4

= 73/2 / 5/4

= 73/2 * 4/5

= 73*2/5

= 29.2 mi/gal.

Red car: Unit rate = 20 4/5 / 4/5

= 104/5 * 5/4

= 104/4

= 26 mi/gal.

The blue car travels the greater distance on 1 gallon of gas.
