720 miles traveled on 60 gallons of gasoline.
 Express this on its Unit Rate.
 To get the answer, we need to divide 720 miles by 60 gallons of gasoline
 => 720 / 60 = 12 miles /gallons
 Thus, in every 1 gallon of gasoline, you can travel 12 miles.
 So, the expression would be like this:
 720 miles / 60 gallons = 12 miles / gallon
 Let’s check our answer
 => 12 miles x 60 gallons = 720 miles.
 Thus, we got the correct answer.
