Answer: Caiden's Car gets the highest rate... 16.2 mpg Ethans car 15 mpg
To "show work" Ethan's car only gives 15 mpg. When you look at the graph where the points are at both whole numbers you divide... 30 miles every 2 gallons..... Well whats one gallon? you the divide 30 by 2 and that is 15.
same as the point (5,60) 60/5 is 15
