A passenger car will go 420 miles on 17.5 gallons of gasoline in city driving. What is the rate in miles per​ gallon?

420mi/17.5gal = 420/17.5 mi/gal

To find the rate in miles per gallon, you need to divide the number of miles the car traveled by the number of gallons of gasoline it consumed.

In this case, the car traveled 420 miles and consumed 17.5 gallons of gasoline. Thus, you can calculate the rate as follows:

Rate (miles per gallon) = Miles / Gallons

Rate (miles per gallon) = 420 miles / 17.5 gallons

Calculating this division will give you the answer:

Rate (miles per gallon) = 24 miles per gallon

So, the rate in miles per gallon for the passenger car in city driving is 24 miles per gallon.
