140 miles on 4 gallons of gas

To express the phrase "120 miles on 4 gallons of gas" as a rate, you can write it as "120 miles per 4 gallons". This represents the number of miles traveled per gallon of gas used.

To find the unit rate, you need to simplify the ratio. In this case, the ratio is 30 to 1, which means that for every 30 miles traveled, 1 gallon of gas is used. To find the unit rate, you divide the number of miles by the number of gallons:

Unit Rate = 120 miles / 4 gallons.

Simplifying this expression, you have:

Unit Rate = 30 miles per 1 gallon.

Rounding to the nearest hundredth, the unit rate is 30.00 miles per gallon.
